Major benefits upgrading to KK over JB? topic

Hello! I was wondering if there were any major advantages to upgrading my already rooted vzwONE and running santod040's debloated 4.3 "rom".

Reason I ask is because I tried to install the ViperOne ROM and realized I wasn't on KK. It looks like a cool rom! But I would probably just be as happy with the NuSenseONE rom.

Advice/opinions/suggestions please!
