 Source for above hierarchy? 
+I based it on which encoder's would reach transparency first based on bitrate. libopus/libfdk_aac/libvorbis/libmp3lame/(ac3 most of the times) should all be transparent at 128Kbps. The encoders listed to the right don't achieve that.
+Any ideas where I could get sources?

 Please explain why it is not recommended to use these encoders or link to other wiki pages that do explain.
 Would personal ABX logs be enough?

+
+The reason for not recommending vorbis, is because it doesn't respect the bitrate given.
