I personaly love both. Like i love the stability and speed of FreezasBareNaked ROM (6.1) but i like the dialer screen of the 6.5 interface. To sum it up, combine the stability of 6.1 and speed. to some of the features of 6.5 and you got a sweet rom
i also hate CHT and manilla. I use SPB Mobile Shell. Best in speed and multitasking.
