1. Horrible: "All shows ripped from FUNimation are hardsubbed and ONLY released in 360p."  This is one of those.  I don't see any HS releases except in 360p for this title.
2. Yibis: Good but slow sometimes.  A lot of folk get one of the quick versions then archive Yibis when it comes out.
3. Absent Others: A lot of groups have come and gone.  There is an endurance factor involved when there are more than 500 episodes.  At one episode per week and 52 weeks in a year, that 10 years of fansubbing.  A lot of marriages don't last that long.  Also, FUNimation hassles groups when they are able.  

Be happy and support those who do what they do so you can have some unique fun.

I suggest watching the same episode by both groups and decide for yourself which you prefer.  Objectively, there is the question of whether one is more thorough than the other in translating everything -signs, menus, songs, etc.  Some speed-subs just do the dialogue and little more.  Then subjectively, see if you think that one group or another makes better sense of the material: the plot, the conversations between people, and the humor.  You don't have to understand Japanese to know if things make sense as presented and whether you were entertained.  If it makes sense, it's probably a good translation of the original, although only those who know both languages can really affirm or comment on that.
