Here's my 411 on these groups.

Live-Evil - Yes, they're good, high quality, and well done, but one thing they lack is information on the cars. Most people who watch Initial D are car fanatics, and I'm pretty sure they want some deeper information on the cars the characters are talking about. Score from me: 9

Animax & AnimeCouncil - Okay, Animax has released a few with Anime-Heaven. I have to admit, their subs are....eh...okay, not too good, not too bad, but their information on cars are top notch. I have to admit, even though I'm part of the group, the quality of the subs are awful, but that's primarily because of Anime-Heaven. Animax only provided the translations, while they were in charge of everything else. Overall, Anime-Heaven ruined Animax's image a bit. This is why Animax is now changing groups to AnimeCouncil. A new group and unlike Anime-Heaven, they provide high quality subs and work. Looking forward to seeing their new versions. Score from me: 8

AnimeOne - Well, what can you expect from one of the biggest fansub groups out there? The only group that provides DVD rips. But the translations ain't up to par that of Animax's info, subs, and Live-Evil's subs. Score from me: 7

AnimeForever - Well, I haven't really seen their version, but from seeing the amount of people that gets it from them, is primarily low. Really low, so I have to assume they're no match to the first three groups. Score from me: N/A

That's my opinions. Everyone elses might be different.
