If I'm going to be perfectly honest I'd say yes, it is definitely worth picking up a pro controller. At least for me the JoyCon never really felt comfortable or as sturdy as I wanted them to be. It made all the difference using a "real" controller while playing games that required much more precision like Mario Odyssey or any of the countless Neo Geo ports by HAMSTER.

Of course there are cheaper alternatives such as the Hori pad or the Wired Controller Plus (which are pretty dang cool) but if you want a solid, well built wireless controller that stands toe to toe with the likes of the Xbox One controller then you can't really go wrong with the Pro controller. :)
