Differences Between Drivers for ODBC Drivers
ODBC Driver for SQL Server
ODBC is the primary native data access API for applications written in C,C++, PHP, Python and others for connecting to SQL Server.
It's widely used in data integration scenarios.
Also, it's preferred if you are developing application on Windows and deploying it to Linux .
SQL Server
The full name of SQL Server Driver is SQL Server ODBC Driver. It’s an old driver since sql 2000. You can use it to connect to SQL Server 2016, but you will not be able to access new features and functionality of SQL Server 2016
SQL Server Native Client
SQL Server Native Client is containing both the SQL OLE DB provider and SQL ODBC driver to support native connectivity to SQL Server and support all features of sql server 2016. It's the best in windows environment
SQL Server Native Client RDA
Remote data access (RDA) in Microsoft SQL Server Compact 3.5 lets an application access data from a remote SQL Server database table.
It can also store, read, and update that data in SQL Server Compact 3.5, and then update the original SQL Server table.
RDA will be removed in the future release, so avoid using it.
So choose sql driver based on the criteria above.
Microsoft ODBC Driver for SQL Server (MSODBCSQL)
This driver was announced in 2013 as the successor to SQL Server Native Client. It is installed with recent SQL Server versions. There are standalone installers for clients. Driver history for Microsoft SQL Server recommends this driver in preference to "SQL Server" and "SQL Server Native Client" for ODBC. Added features over "SQL Server Native Client": driver-aware connection pooling, connection resiliency, asynchronous execution (polling), support for Always Encrypted, recent SQL Server compatibility (including Azure SQL), and more supported operating systems (including Linux and macOS). You can follow current development on the SQL Server Blog (with previous posts on the SQLNCli team blog).
Driver={ODBC Driver XX for SQL Server} (XX replaced by driver version. See System Requirements, Installation, and Driver Files.)
SQL Server Native Client (SQLNCLI)
Introduced with SQL Server 2005 and ships with SQL Server (also installable via sqlncli.msi from SQL Server feature packs). Added features over "SQL Server": Multiple active result sets (MARS), user-defined data types (UDT), query notifications, snapshot isolation, and XML data type support. The version for SQL Server 2008 also added support for the new date and time types.

SQL Server Native Client RDA
Remote Data Access (RDA) is a SQL Server Compact feature which "lets an application access data from a remote SQL Server database table." I can't find much documentation, but it appears this driver was intended to support replication scenarios with Compact Edition.
SQL Server (SQLSRV32)
Included in Microsoft Data Access Components (MDAC) (now called Windows Data Access Components (WDAC)). This driver is available by default on Windows (since 98 and NT 4.0).
Driver={SQL Server}
To check which drivers you have installed, fire up an powershell (32/64 bit - depending which driver architecture you want to use) and run
OLEDB
(New-Object System.Data.OleDb.OleDbEnumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
ODBC
Get-OdbcDriver | select Name,Platform
Overview
https://docs.microsoft.com/en-us/sql/connect/connect-history#odbc
There are three distinct generations of Microsoft ODBC drivers for SQL Server.
- The first "SQL Server" ODBC driver still ships as part of Windows Data Access Components. It is not recommended to use this driver for new development.
- Starting in SQL Server 2005, the SQL "Server Native Client 10.x/11.x/12.x" includes an ODBC interface and is the ODBC driver that shipped with SQL Server 2005 through SQL Server 2012. It is not recommended to use this driver for new development.
- After SQL Server 2012, the Microsoft ODBC Driver for SQL Server is the driver that is updated with the most recent server features going forward.
SQL Server
It's the old one from the MDAC-package (https://support.microsoft.com/en-us/help/899456) which now (since XP/2003) comes with the Windows-OS. https://docs.microsoft.com/en-us/sql/connect/connect-history#mdacwdac-releases
https://docs.microsoft.com/en-us/sql/relational-databases/native-client/applications/updating-an-application-to-sql-server-native-client-from-mdac
...starting with Windows Vista, the data access components are now called Windows Data Access Components, or Windows DAC). Although both provide native data access to SQL Server databases, SQL Server Native Client has been specifically designed to expose the new features of SQL Server 2005 (9.x), while at the same time maintaining backward compatibility with earlier versions.
SQL Server Native Client
https://docs.microsoft.com/en-us/sql/connect/connect-history#odbc
SQL Server Native Client is a stand-alone library that is used for both OLE DB and ODBC. SQL Server Native Client (often abbreviated SNAC) was included in SQL Server 2005 through 2012. SQL Server Native Client can be used for applications that need to take advantage of new features introduced in SQL Server 2005 through SQL Server 2012. (Microsoft/Windows Data Access Components are not updated for these new features in SQL Server.) For new features beyond SQL Server 2012, SQL Server Native Client will not be updated. Switch to the Microsoft ODBC Driver for SQL Server or the Microsoft OLE DB Driver for SQL Server if you want to take advantage of new SQL Server features going forward.
SQL Server Native Client RDA
Came with .NET Compact Framework 3.5
ODBC Driver for SQL Server
https://docs.microsoft.com/en-us/sql/connect/connect-history#odbc
After SQL Server 2012, the primary ODBC driver for SQL Server has been developed and released as the Microsoft ODBC Driver for SQL Server.
MSOLEDBSQL - Microsoft OLE DB Driver for SQL Server
This driver has been deprecated and later undeprecated:
https://docs.microsoft.com/en-us/sql/connect/oledb/oledb-driver-for-sql-server#3-microsoft-ole-db-driver-for-sql-server-msoledbsql
The new OLE DB provider is called the Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL). The new provider will be updated with the most recent server features going forward. To use the new Microsoft OLE DB Driver for SQL Server in existing applications, you should plan to convert your connection strings from SQLOLEDB or SQLNCLI, to MSOLEDBSQL. https://blogs.msdn.microsoft.com/sqlnativeclient/2018/03/30/released-microsoft-ole-db-driver-for-sql-server/
