Default Is galaxy note 3 worth it?

How good is galaxy note 3 with rooting?

And if i want to do a OTA update, how will i then proceed?

CAuse i want a new phone that has:

Easy to root support (and unroot for ota updates) and easy to fix in case a root goes wrong and bricks without sending it to pay loads to reset the software
Big screen
Fast and has a good battery
supports OpenGL 3.0 (for dolphin emulator)
Can record in slow motion (720p 120 fps like iphone 5s can, or better)
Supports most new gameloft and other big games
minimum 1080p
Good camera
