I'm not sure. I wouldn't call myself a power user, but a mere tinkerer. I think the system is simple, the new-ish arch-install package (I'm not sure if it's currently packaged in the iso) uses a simple repl to pick features like desktop environments and whatnot.

the best distro is the one that works for you. I like debian and arch because they're simple and easy for me to use for simple programming and other such things.
