Pretty close
(Note: I only used it for a day, then returned it since I wanted to get a first party controller.)
It gets surprisingly close to a pro controller without being a pro controller. It has motion controls and feels mostly the same, save for the shoulder buttons which feel a bit hard to push, although I'm comparing it with a pro controller I owned for a year, so it may be worn down a bit. Visually it looks like a normal pro controller just without the usual logos.
The biggest difference however is that the hd rumble is just gone. This controller does have rumble, but only a binary hard rumble off and hard rumble off. This can be a bit of a pain for games like Splatoon which has a subtle rumble for when you are swimming which just becomes constant vibration with this controller. Granted, you can turn rumble off though, so it's not a complete dealbreaker.
I'm not sure if getting rid of hd rumble is worth $20-40 of cut costs, so there may be some other differences I haven't run into.
Unless there are some long-term issues that I haven't run into yet, this should be an alright substitute for a first party controller.
