Best rear derailer for 2019 Trance E Pro 1

[KatoomXC]

Was just looking into one of those new fancy wireless derailers from SRAM but I don't think those will work as they require the frame to be UDH ready which I'm pretty sure I'm not.
So what is the best bang for the buck detrailer, currently running the SRAM Eagle NX which I find to be kinda slow at shifting and clanky under load.

Shimano SLX.

Pretty much any SLX is the best bang for your buck, unless you start to experiment with brands you have never heard of.

If you need to stick with Sram, I always had a good experience with GX.

GX AXS would be my vote if your 12s
