Sorry, but all those vs. threads are pointless, and probably will end up in arguments..
It's a matter of personal preference..I prefer Sakura because it's more practical for me, I tend to use multimedia a lot, especially movies, and besides it look perfect to me, it's very skinnable and I can custom it perfectly to my own pleasure..
No doubt, AKAIO has better support, and is much faster updated, in my opinion, it's not as pretty as Sakura, and it doesn't have direct support for multimedia, but Moonshell is there to solve that problem..
In the end, I say this is pointless because people will vote for the firmwares they use..
