I'm another that one that would suggest the X1 elite, best controller I've had. As far as the paddles, they are sensitive, but it's something you have to adapt over time and you wont have issues. It's hard in the beginning especially if you grip your controller hard like I've do. Also like some already mentioned paddles can be removed. At this point you should wait for a sale on it at there has been a few that has brought it down to $100.
As far as scuf, I bought myself one this past year . The scuf impact, after contemplating whether to get one because I read people have a lot of issues with them and eventually something breaks. After a few months of the impact being out and a lot of people giving it good reviews I decided to pull the trigger. A week after its 6 month warranty the L3 button stopped working. The L3 button is sprint on most games. When it worked it was a really damn good controller and I liked it much. At this point I wouldn't recommend scuf to anyone.
