What Type of Wipe does one Perform before flashing a new rom?

[AlexOnVinyl]

I use 4ext for my Recovery and here are my options for formatting/wiping before installing a new rom

Which one of these do I want to do?

And the last few options:

Wipe Data/Factory reset. That's it for ROMs.

I've also heard to make sure you clear out your cache files too prior to starting a new ROM. Hope your new ROM is running as smooth as butter! :smokingsomb:

Actually it's a factory reset, wipe cache, wipe dalvik cache when flashing new ROMS
