Should I buy?

I currently have the Razer Kraken 7.1 Chroma which is pretty old, I think I've had them for about 4 years now.
I've had a look around and the Logitech G PRO X has come to my attention and I'm considering on buying them.
I want to buy a new headset as an upgrade, not because it's new. Any help would be appreciated.
I'm considering all factors to do with the mic and speakers.

Steelseries Arctis 7

Stick with razer, get the newest kraken

I don't think anyone makes better mics

When I bought mine, years ago, I chose Kraken also for the mic/ nice voice quality

That was my no.1 criteria, but only because I was talking with a woman in the US

Regardless I recommend you get Razer again. Trumps everything else
