I've played a lot on mouse and keyboard and controller now and a lot on shared servers and controller servers.
My opinion is that most players in this game will have a more enjoyable time on this game by sticking to controller servers if they are controller players.
For different reasons than others will say though,
A lot of players will say because of cheating or skill, controller servers have more consistent skill but that's only because a lot of the brand new players end up on shared/pc servers.
The reason I think that a majority will enjoy controller servers more is that most of the player content creation is on pc servers, that changes the ecosystem of servers dramatically.
Controller servers are far more about the experience and pc/shared servers are far more heavily focused on the content/clips/twitterverse
If someone is here specifically for organic adventure with pvp just being a part of it and they use controller I highly recommend sticking to the controller and controller servers. Far better resource for organic adventure scenarios and encounters.
