HELP!! need help deciding between ad700x vs akg k702 for competitive console gaming

The headphone i currently own is the sennheiser hd 558, and i am looking to upgrade my headset to something better for fps competitive console gaming. Based on the research i've done is that the akg k702 would need something better to power it better. I am also looking for a good amp or dac for my headphone's. I've been looking at the creative sound blasterx g5 7.1 would that be any good for these headphones. The console i own is the xbox one.

I have both the ad700x and akg k702 (Austrian version with bumps). I prefer the k702 as I find the sound more clear. I use the Astro TR mixamp to power it. As far as soundstage and imaging they are pretty close to the same at least for me. But Because if the clarity of the k702 I think I’m able to find enemies better. I found the ad700x a little harsh on my ears with the some sounds when playing FPS games.

i have had a pair of ad700's (non-x) for 9 years (egad! i never realised it was that long), and use them for desktop gaming occasionally, but mostly for listening to lossless flacs , more recently using a little cmoy (altoids) portable 9v amp the sound stage is excellent, and the bass enjoyable for me, but i am an acoustic / jazz / vocal / steely dan style listener, rather than a hip hop fan ymmv
