Question [Q] Huawei G700 - Which ROM + Overclocking?

Hello XDA,

I have the Huawei Ascend G700 (click for specs). I've known from previous experiences that flashing another ROM is a good thing for better performance and I don't like the Huawei Theme anyway.

Information You Need
AndroidTM 4.2(Jelly Bean)
Huawei Emotion UI
Quad-Core 1.2GHz processor, 2GB RAM

Now I'm asking, which ROM would you guys advice for my phone? Pro's and con's are welcome!
  • AOKP
  • CyanogenMod
  • Liquid Smooth
  • Illusion

Since I'm a complete noob, which tutorial do you guys advice for not bricking my phone. I've done a Dronix flash before but lost my stock ROM I think so backup needs to be covered. YouTube links are welcome!

XDA - [Tutorial] Root, Unlock, Recovery and flashing a Custom ROM
XDA - Flashing Guide - Android
Youtube - Android Tutorials [15] - How To Install Any Custom ROM On Any Android Device

Are these good tutorials? There are so much but most of them don't cover every step clearly...

Also, how far should I overclock the 1200MHz processor so I don't melt my CPU down? I've read the rule of thumb is to overclock only 20%, so 1440 MHz would be a good choice?

Sorry for the noob questions :)
