>>173512That highly depends on how you define 10/10.
If you want something with high appeal to all audiences and yet high popularity to quality ratio like FMAB, then there are Death Note, Code Grass, Steins Gate or TTGL.
But there are 9/10 at best if you ask seasoned veterans. There is no absolute answer to your question, but some answers that might pop up are Tatami Galaxy, Katanagatari, Shinsekai Yori and Serial Experiments Lain.
I think both Normie's and elitists will rate Cowboy Bebop at 10, though.
