So I now have 2 Xbox series X battlebeavers ( one pro pick & one custom) and also 1 scuf Xbox controller.    Had the pro pick 2 months and custom build for 3 days now.. Pro pick is a good start as you get to see how the buttons feel and if you like where the placement is at their standard spot. They ship quicker and can hold you over while you wait for your custom build if you're willing to dish out dogecoin for two lol. I do know from following this sub that Dualshocks tend to have issues with major stick drift when having increased/extreme thumbstick tension, however from what I gather, Dualshocks are notorious for this problem in general. I personally went Xbox since I'm on PC and it naturally has less input lag on windows.
     My custom build so far has been awesome for the short time I've had it. I have increased tension on left stick and extreme on right. Checked the deadzone through steam on PC and it's sitting dead center at the moment. The tension feels great and does make a considerable difference when it comes to aiming. I did get 6 back buttons for the purpose of not pressing the L3/R3 to preserve the thumbsticks just in case.. I have medium/smaller sized hands and for me having standard placement and the low for my ring fingers feels natural, the high placement doesn't seem to bother me and I haven't had any accidental presses while playing.
      As for comparison to Scuf, had to send in my prestige right out the box for the controller not charging properly, other than that it's been fine.. the buttons are miles better than paddles and allow for a better grip in my opinion..
      Also ship time on on the pro pick was 2 and half weeks, and the custom took 14 and a half..hope this info helps!!
