Which Pro Gaming controllers are supported or are working on iOS 13.3.1

Hi I'm wondering what pro game controllers are working with iOS 13.3.1. I am currently using a PS4 DUALSHOCK which is working flawlessly, but I’m ready for something with more precise controls, and bottom controls, along with remapping capability. I’m playing on my 2nd gen iPad Pro 12.9 and iPad Pro 3rd gen 11. I’m assuming that if a controller works on iOS it will be the same on a current MacBook Pro running Catalina.

I am looking at buying either a SCUF Vantage 2, SCUF INFINITY4PS PRO, or XBOX Elite 2 game controller. I’m wondering if there are any issues of being not compatible with this iOS? Like seeing digital bumpers, remapped bumpers, or any other issues? I play mostly COD Mobile at this time. Thank you in advance for any information you can share, based on first hand experience using these controllers.
