I really liked Arcueid's route, but disliked every other.
Ciel's route was okay.
Akiha's was weird.
Hisui's was horrible.
And Kohaku's route was kinda good.

And the H-Scenes are just wtf. I guess they have some funny lines, so I've heard at least - I skipped every H-Scene.

I didn't get to read the remake yet, but considering it doesn't have H-Scenes it is probably better to read that, although it is harder to acquire.
