Sorry, but I have only watched the show from SubDESU, so I can't compare it to others. The video has good colours, the sharpness isn't what you'd get from BDs but looks pretty standard aired clarity to me. File sizes aren't humongous, so at least I'm not "paying" for any quality that wouldn't be there in any case, in aired eps.
Based on
ji-hi's fansub comparison the video quality is comparable to Hiryuu. However, the translation is better than Hadena's, which barely makes sense based on the shots on the comparison page (certainly I can already see why you'd say Hadena has good video but bad subs).
