If you want minimal tweaking, I think you're pretty much constrained to Gnome and/or KDE as those are the two desktop ecosystems on Linux. Just install both and switch between them for a while until you decide which one is for you... most applications won't care which they're running under. FYI, a lot of the dislike for the current Gnome comes from remembering what it used to be in the Gnome 2 days. You have no such history so maybe it'll be fine for you.
