versatile

sure. idk about "the most", i haven't seen it do anything that other DMs can't do with some tinkering. hell just installing cairo-dock yields a very similar ui experience imo.

usable

i can't agree, my experience is things not staying where i put them, random crashes, layout and themes not "sticking" between logins, and occasionally the entire session crashing - all this from a fresh install on an untinkered-with system, and it's been a consistent experience through the years. maybe you're luckier than i am?

best applications

i never met an application i wanted to run that i couldn't because i had the wrong DE. what are you talking about?
