When it comes to the basics the N30 Pro excels, with an excellent d-pad that bests both the Xbox One and the Switch Pro controllers. The face buttons are also "just as good" according to PC World, "emitting a satisfying click when depressed." The thumb sticks weren't as nice, with Destructoid noting they "don't provide much resistance" compared to those on console controllers. However, PC World feels they're at least better than the sticks on the PlayStation Vita and Nintendo 3DS.
The biggest issues with the N30 Pro is how it positions its shoulder buttons. To achieve its classic-styled slim profile, the buttons were placed next to each other along the edge, making it very easy to hit the wrong one and necessitating a grip that The Verge found cramped and uncomfortable.
If you're looking for a better gamepad for your Nintendo Switch, it's best to go with the Pro Controller. But once the Virtual Console is out you'll probably find yourself itching for something a bit more period appropriate but still versatile, and for that the N30 Pro fits the bill nicely.
