Nyoro~n sucks. Don't listen to the idiots who say "Nyoro~n has decent subs" or "Nyoro~n is getting better" because they're just idiots.
Shinsen is on the "If everybody else sucks, I'll just stick with these guys with no real loss" level of quality in translations, but they fag up stuff here and there, like official names.
Conclave-Mendoi is the best and only subbing group you should be sticking to, but given their current speeds, it'll take a week to a month for them to spit out subs, so until you get their subs, just stick to Shinsen for speedsubs.
To make a car analogy...
Nyoro~n is a Honda Civic, idiots think it's "quality".
Shinsen is a Lexus, decent and good all-around.
Mendoi-Conclave is the luxury Cadillac, the epitome of quality.
