I like the Bible Black style more than the Taimanin Asagistyle. In Taimanin Asagi the sex-scenes are animated to fast, it's kind of annoying. Bible black has the same quality but the sex-scenes are less chaotic.
Bible Black is my all time favorite series, so I like it's style the most.
I personally prefer more romantic hentai, granted their is a large amount of rape, tentacles, etc. I quickly skim for the ones with possible woman initiating the sex or the random romantic comedy hentai.
I've been a big fan of 3D hentai lately, but the majority of them are just not my style. Umemaro3D is probably my favorite of that genre. Otherwise, I tend to stick with the cute style of Hentai.
