Usually if a group is releasing weekly alongside HS but a few days later, they are better than HS. They basically make small corrections (or none at all) to the crunchyroll subs and they take the video source from somewhere else (either TV or some foreign streaming service).
Asenshi, Doki, GJM are ones I can recommend. At the same time, I don't really give a shit and always get HS because they are faster and I don't feel like the improvement is worth waiting a few more days to watch the episode.
Try to steer away from commie, FFF, Vivid,… basically if the dialogue contains too many cursing, internet slangs/jokes/memes, you should start being wary of it. Though these days commie sometimes just rips stuff without making any "funny" modifications (like Fune wo Amu), I still feel like downloading them is like a Russian roulette.
Where are these reviews from? Either way I don't think they'd be good anyway, because a lot of people don't mind, and sometimes even like, when the translator has some "fun" with the script.
