With all the UnitFrames out there i just dont know which to chose. I wanted to here the suggestions of others...
I use Discord right now and i want to change...so what UnitFrame has the most similarities to Discords version?
The thing with DUF is that it is so configurable that you can have it look like anything that comes into your imagination. Because of this we can't recommend a unit frames replacement for you. The solution is to try them all and choose the one that you like as Indy suggested.
Personally, I like ag_UnitFrames with the PerfectRaid setup - before that I used MiniGroup2.
not a big fan of oUF, but I'm liking AG_unitframes. I switched over from Discord too, but I'm sticking with DAB (tried bongos, bartender, pubcrawl, etc, nobody has the one feature I want), DART and DFM for now.
Nirek: You might want to look into XPBarNone. Gets you a very nice and flexible XP/rep bar, without having it tied to any particular unit frame.
I like ag_UF. I've tried oUF a few times, but kept being driven away by the awfulness of the configuration dewdrops. I mean it: those things actively discouraged me from feeling like oUF was worth using.
This may have changed; I saw ckknight check something in to tweak them, so I guess I'll have to give it another try.
