1. Variety, i love anthros, but not exclusively.
2. Although i do wish skin edits were allowed without them being by the original artist, i like that this place isn't filled with edits to cover the subject in racist tattoos.
3. The comments here are (usually) a lot funnier and the commenters (from my experience) don't end every post in some obnoxious catchphrase or other crap i'd downvote.
4. If i start a thread here (really wish i could start threads on 4chan though) it'll get SOME activity because it doesn't have to be exclusively about sex or whatever the site's general theme is.
5. This place doesn't seem to have the security problems e621 has.
As for what i don't like about here
1. Captchas, need i say more?
2. If i'm being honest i wish that certain kinds of hentai were allowed here that aren't.
3. I also wish that if someone uploads particularly unpleasant things (Gore, Snuff, Piss, Scat, Farts, Torture, etc.) they'd have to tag it as such instead of using a few relevant tags but not the big nasty ones so people like me don't EVER have to see it.
4. The inability to edit comments, i've fucked up jokes and references and made plenty of typos and it irks me.
That's all i can think of right now.
*EDIT* 5. Not being able to add combinations of tags to our blaclists.
