Besides the ability to set an "activeClassName" and "activeStyle" on NavLink, is there any reason to use NavLink over Link when creating links to other routes on non-navigational elements (ie. not main nav in header or footer) on your site that don't need an active state/class?
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.
