[Q] Update it or not? Newbie

[H.T.C]

I've bought huawei g6 today, this is current firmware

Android version - 4.3
Emotion UI version - EmotionUI 2.0 Lite
Baseband version - 203017
Kernel vers - 3.4.0+
Build number - G6U10...
Custom version - CUSTC...


but I really like how EMUI 3.0 looks, what do you think about upgrading is it worth it, the phone is stable and fast now, have somebody installed new fw yet and where I can find it?

Thanks in advance
