I haven't gotten to the PGA Tour in my career yet but from the videos I've seen others have also had the -10% power problem on drives with driver. The partners play well about 90-95% of the time but that 5-10% has some weird results.
They don't play well in short game, they always use the blast out of the bunker and end up 15-20 ft away and have trouble getting up hills with the pitch shot, often leaving it short. They seem to only use basic shot types, never the punch or flop even, no pick out of the bunker or finesse approach, etc. Not a huge fan of the way they putt, I think they take the putt read line and putt off that, which usually means they end up 1-2 ft away when they miss and the game will "simulate" 3-putts by having them miss a couple of those 2 footers. I'd like to see more variety in the putting, some misreads or ones that go way long or short. Overall I like how it's done but there's some rough edges to iron out.
