It's not just any collection of cartoon hardcore, it's the one and only. The Hentai Collection is named in such a way to ensure that it attracts the attention of lovers and fans of Hentai material. Unfortunately, they don't tell you before you sign up that your membership is merely a repetition of a number of different videos from another site in the network, namely Ultra Hentai Pass.

I say a number because the latter site offers way more content. Currently, your membership to the main site would give you 24 hardcore movies with numerous cartoon situations. However, if you check out UltraHentaiPass, you'll be given a selection of 70+ videos, some of which are identical to those offered on TheHentaiCollection. If you like cartoons and a wide variety of non-anime material, the content on either of these sites will suffice. However, I'd go for the bigger site if I were you.
