Gamesir and 8bitdo have dogshit internals and most importantly dogshit d-pads.
Vader 4 Pro is currently the best all round, non specific pad in the industry outside of the Wolverine V3, the Vader 5 is borrowing features from the V3 such as an additional set of bumpers which is much better than the Duke style 2 extra face buttons, but costs considerably more than the 4 Pro.
The Direwolf 3 is also a decent option if you don't care about all the fancy stuff the 4 Pro has such as gyro, two extra face buttons and the like.
