Default [Q] Easier to root from MI9 or MJ7?

I'm still running MI9 and keep getting hassled to take the OTA update. From what I'm reading, it's easier to root and not lose data from MJ7. But, it'd be nice to get the de-bloated Beans Stock coming from rooted MI9 as well.

I've been out of the game a while and a lot has changed. Not 100% familiar with some of the newer hacking terminology. My main goal here is to run WiFi Tether and have the latest radio and updated software (fewest bugs/hang ups the better).

Which method is less hassle?
Galaxy Note 3
Rooted/SS installed
Jelly 'Beans' B4
