Question JB 4.3 vs KitKat 4.4.2

Hello everyone,

Since there is still no proper root and recovery for the M2 on KitKat, would someone who has upgraded from JB to KitKat be able to write their experience with KitKat so far? Are there enough KitKat advantages over JB 4.3 in order to upgrade while losing root? Is it maybe better to wait until a proper root and recovery is available?

Thanks and all best.
