React Router v4 <NavLink> vs <Link> benefits

The official documentation is clear:

<NavLink>

A special version of the <Link> that will add styling attributes to the rendered element when it matches the current URL.

Thus, the answer is NO. There are no other reasons except the mentioned one.

When you need to use style or class attributes on active <Link>, then you can use <NavLink>

Let see the example:

Link

<Link to="/">Home</Link>

NavLink

<NavLink to="/" activeClassName="active">Home</NavLink>

Link Component

It is used to create links which allow to navigate on different URLs and When we click on any of that particular Link, it should load that page which is associated with that path without reloading the page. Example:

NavLink Component:

If, we want to add some styles to the Link. So that when we click on any particular link, it can be easily identified which Link is active. For this react router provides NavLink instead of Link. Now replace Link from Navlink and add properties activeStyle. The activeStyle properties mean when we click on the Link, it should be highlighted with different style so that we can differentiate which link is currently active. Example:

Simply, When you use <Link> there isn't any active class on selected element.
In contrast, with <NavLink> the selected element is highlighted because this element is added an active class.
Hope useful for you.
