I use it without issue and frankly couldn’t live without the customisation of it now. The only problem I’ve had with the Steam Deck is the background recording no longer works (consistently) as far as I’m aware this is an issue with Steam/SteamOS and not because of Decky

I have to be bit against decky. Out of the five steam deck crashes I’ve had past year all of them were because of decky frontend. At least that was what the crash report said and it had also option of disabling decky until next reboot. So my experience was decky crash -> no decky&happy -> system upgrade -> decky crash -> no decky &happy -> system upgrade… rinse & repeat

I’m not a decky (or steam deck) power user and last I checked the uninstall was not trivial so take my opinion with a grain of salt. I wish I never installed decky.
