I've given the PC version a go also, and it is easier to hit targets, obviously dependent on your own skill level with each input too, that's the biggest difference. It plays differently though and not in a way that is better or worse because everyone is more accurate, and characters like tracer actually feel more vulnerable.
On console, you can't react to things as quickly, or be as accurate, so that might seem like a disadvantage for tracer, but it's not. For instance, you're not going to be sniped randomly, or headshot by something like Mei's right click. It's just very unlikely, and in general it affects gameplay balance a lot. Tracer can get away with a hell of a lot more on consoles because her hard counters are less effective and players are slower to react to her teleports.
Inherently, the reduced accuracy on console makes non-accuracy dependent characters more viable as they do not suffer as much from their low damage output, benefiting more from the fact that they consistently, easily hit their targets. This makes characters like Mei and Winston more effective as console players strip their health slower (reduced accuracy) but their damage remains constant due to easy to use primary fire.
As I say, in terms of what you can actually do with each character it's not better or worse but different, and the controls, while they do feel a little bit off, it's not glaring, it's not as if the game suffers input lag or anything of that sort, it just doesn't feel as natural or as nice to play as the best the industry offers on console platforms. Hopefully if enough people complain about it, they fix that element of the controls then I'm sure the differences wouldn't be as significant. If you have seen some of the better Call of Duty players, they certainly come close to the accuracy achieved on PC, but a large part of that is that the game is designed to control really well, and it offers an appropriate level of assistance to compensate the less accurate controller.
