Very good read. I think some mention of battery life would not be out of place (for the non-wired cases): for me that's the main drawback to the otherwise great Dualshock4 (a secondary one being that nobody seems to know what to do with that touchpad).
Having played most of BOTW in the "arms in random places holding split joycon" pose I'd say the joycon work a lot better than one would expect from looking at them. I do have smallish hands though.
I'll have to give that SN30 Pro+ a try. I'm definitely a fan of the look. These days I'm using an XOne to game on PC (in particular the "Patrol Tech" version which was on sale, and is a tiny upgrade over the default but not as expensive as the Elite variety) but better program-ability would be welcome.
