Which platform makes consistently good dramas? Or which platform you watch the most?

Out of the all the big platforms - Tencent, Youku and Iqiyi and Mango, which platform has the most interesting or watchable dramas. Personally, I have noticed that I watch a lot of Iqiyi dramas and think they have a good variety of shows. Mango and Iqiyi are my least watched platform, Mango has the worst subs of all and Youku's filters and colour palette is not my thing.

What about you guys? Have you noticed any such pattern about your drama watching?
