I'm unaware of any pro gamer (or streamer) that's using PS/2, and that's about as serious a gamer as you get. Most are using a late model mechanical keyboard connected via USB, often with lots of RGB just because.

I think the only PS/2 holdouts you'll find are the old Korean Starcraft players that are still using a Qsenn DT-35.

PS/2 supports lots of RGB, I'm using one, because using the USB costs CPU where as the PS/2 does not, and PS/2 gives NKRO and lower latency, however insignificant they are.

It's entirely a preference based thing, the most relevant factor would be whether or not you need to hot swap it.

Pro gamers are paid to use whatever their sponsors want them to use. And if their new fancy keyboard is good enough not to negatively affect their game, I don't see why they would turn down the money.
