I've been on KDE for about 11 years now. Love it!
I have 3 SSD's in my machine.
Drive 1: a big, heavy, feature-filled version of KDE Neon (with Snaps disabled) for the latest widgets and features as my Daily Driver for surfing, email, calendars, documents, etc.
Drive 2: Debian 14 rolling Testing for playing with sketchy home theater, AV, and piracy softwares. (I regularly wad it up and reinstall from a ResueZilla image.
Drive 3: A stripped-down to the bone version of Debian 13 on a LUKS encrypted drive, used only for touching my most precious crypto wallets.
