What you should be concerned about is not only key feel, but also latency. And the MX Keys is good at neither when it comes to gaming.
The keys have about 2 mm of travel and feel like a standard, if quality, membrane keyboard. And it uses the standard Logitech wireless dongle instead of the Lighstpeed one, so there's significant input lag and that will wreck your k/d. Unless you use it wired, then the latency should be negligible, but still it isn't a top gaming experience.
The GG915X has different switch options, feels good to type and performs great in games wireless or not. I'd look that way if you're serious about FPS games
Logitech G915 X perhaps? Love my TKL and probably only needs charging once every 2/3 weeks (USB overnight jobby).
It's a tad over budget but keep an eye on the sales.

Elite gaming performance, deep customization, but divisive typing feel.
