Keep sucks and everything they've done has recently, they're really slow on everything and still manage to do a job no better than a group that takes a few days to make a release.

Chihiro is a speedsub but fine considering its out in a matter of hours.

You can tell which one I prefer. Though they did make one or two translational errors I'm not particularly pleased with, and in many ways is a bit of a spoiler, Lunar gets the job done fast and with a good amount of quality.

At least Lunar doesn't screw up the whole plot of a series with a translation. I'm refering of course to Keep's Grenadier and "Enlightened" for 'senshi'. The ones in Bleach aren't as glaringly bad, but still not particularly close to the actual meaning.
