HorribleSubs doesn't sub its releases, all they do is rip anime's off Crunchyroll -- thus resulting to a fast release. However, the accuracy of the translations are so-so.
As for Taka, they are still trying to catch up with the series, and they are pretty slow at releasing because they actually sub their anime's. The accuracy of their translations are great though.
I personally like Taka because of the quality, accuracy, and their release formats (.mp4) because I watch my anime's in my iPhone. Also, they do karaoke's for openings and endings of each and every anime they sub.
