What's the issue with Horriblesubs?
Why wouldn't you watch their releases? They are episodes originally subbed by CrunchyRoll, so they should be pretty good? 
The translations are usually fine, since - as you say - they're done by CR. But they make no effort to maintain any kind of reasonable quality level, and their releases are generally very poor in all aspects other than TL quality. The size of their videos tends to be unnecessarily huge considering the poor quality, too.
Personally though, I dislike them on principle more than anything else. At least most fansub groups actually make some effort to justify doing what they do - even the ones which don't create their own translations work hard to ensure they offer the best video quality, typesetting/subtitle quality, chapters, etc that they can. HS just rip off CR's work and upload it themselves for free.
(And yes, I know there are other groups which just rip stuff and make no effort to improve on it. I don't like them either.)
EDIT: Also, on topic:
I wish they'd hurry up and tell us what happened to Eren. The way it's been presented, I find it hard to believe there's any way he's really dead, but they're taking their time explaining it. I really want to know! I was on tenterhooks all the way through episode 6 waiting to find out, and I never did
