Tough one... if we're talking about every visual novel available now, and I had to limit myself to one type? I'd probably... have to go with galge? There's just far more variety, so, the ceiling for my preferred form storytelling (plot heavy/charage) feels higher?
I get a little giddier reading yuri personally, but there's barely any visual novels that fit the criteria (Flowers series, Ever Maiden, the Nurse Love games if you want to get soap-opera-y with it, Yurirei, then of course the goat aka Seabed, being the only ones I can think of currently) with BL there's deeeefinitely more variety, doubly so with otome, but, yeah... I just love the element of choice... I feel sad just thinking about it though haha.
