Here's a secret. Most Linux Distros are the same, and at the end of the day you have total control over the machine.
Alpine for lazy server admins that want a light, secure base install while being easily adaptable for anonymity.
Debian repositories for normies because you'll be fairly stable. You'll be able to patch exploits and bugs fairly quickly with Debian. You can still replace SystemD with something like OpenRC if you wanted.
Gentoo for no-life techie because you have full control and responsibility over how to compile all packages.
TempleOS for a Commodore experience but with HolyC just in time compiling. Good for distractionless programming since it has no networking.
Qubes and Whonix for your isolation and anonymity needs, useful for war-drives. Qubes will isolate apps and Whonix will isolate workspaces from exploitation and route to Tor. You can install additional apps such as other anonymity networks like i2p.
OpenBSD for your isolated laptop disconnected from the internet to deal with personal agendas like finance. Transfer info from a secure isolated channel into an encrypted volume on USB then swap to secure laptop. Wipe the USB after. Read up on stuxnet Or just find a way to use pen and paper, and fire.
