I have the ROG Centurion 7.1 headset. It's quite amazing, though long-term comfort isn't there as the headset runs a bit tight (on my big ass head at least). Great if you want a true 7.1 surround headset!
As for your mic, if budget allows, I highly suggest an external setup. I have a Scarlet CM25 condenser mic connected to a Scarlet amplifier and a cheap desk-mounted mic boom that I bought from Amazon. Quality is fantastic and I get a lot of in-game compliments for how clear my voice is. It's also good at filtering out background noise; a lot of times I'll play games through my JBL studio monitors (also routed through aforementioned amp) and never get complaints of hearing the game or my keyboard/mouse clicks with an open mic in Discord. I know headset mics tend to pick those up especially when using sound detection over PTT.
Edit: Didn't see budget post. I'll keep my post up just in case, though.
