I'm a mechanical keyboard aficionado - I've gone through everything from Das, to Annes, to WhiteFoxes, to Keychrons. (Yes, I did solder some of those...lol).
My current daily driver is a Keychron K6 - but even I am seriously considering this Logitech.
The spec sheet promises a battery life of 10 months (no backlight) - the Keychron K6 is fine - except that the battery life sucks, and it takes 3-4 seconds to wake up from sleep every time.
I'm looking for a QMK wireless keyboard, but they're thin on the ground - and I suspect the battery life would still be terrible.
At the end of the day, companies like Logitech (or Apple) have the time and engineering nous to test things, and have them Just Work. Things like decent battery life, or having fast wake-from-sleep would probably be handled by their engineering teams.
