Hentai as in perverted and erotic content
Deathnote is good - I catch it on Adult Swim sometimes.
Well, even then it is a difficult advise, there are to many genres... But if you want to "get in" into Hentai, stick to the "classics" (Although most people would argue what the classics are

)
If you are looking for series:
Try:
Bible Black (New Testament are better)
La Blue Girl
Daiakuji
Personal advise: Bible Black: New Testament and Dragon Pink
Oh.. if you are looking for hentai games, there is a whole bunch of descent once out there. In an unlikely case that you are into RPG (Role Playing Games), PLEASE try "Sengoku Rance". Do not read any guides, just get the game, get the English translation patch and play it a couple of times, then read the walkthrough to see if you had missed any endings or scenes

If you need more advice, be more specific about what you are looking for because most of the request for "good Anime or Hentai" go unanswered cause there are to many different style, genres, etc.
PS: Deathnote is a kind of psychological thriller, why is it on an "Adult" channel?
