Nah, of course I know about those host too, because I have been around Chinese forum in years to get CGs back then, even rayfile, junkfile, howfile or whatever, but not much now ^^
In my opinion, 115 and jshare is quite fine, but in my timezone GMT +7, download speed always lower than 80kB/s around 6 - 11 PM...And because of Chinese interface, people may not able to download, not talking about you need register an account to download big files...
I also looking for new better hosts to store my files, but none so far, blame to those stupid laws S.O.P.A, P.I.P.A and A.C.T.A...>_<
