ATT to DevEd to WWE??? Just a few simple questions

Hey guys, very easy question today but I can't seem to find an answer anywhere... I'm s-off, super-cid, unlocked, rooted, 3.19 boot, currently running the a converted DevEd from stock AT&T... Most custom ROM's are built on the WWE base... but it has a different model number than I have... 0p6b10000 vs 0p6b12000... Do I need to change my mid to flash the WWE RUU? Does the proper base for a custom ROM even matter as long as my bootloader and firmware are up to date? I mean am I miss out on any features by running a ROM over DevEd vs WWE??? Just curious.


Edit: BTW, I know how to do everything I just asked about.. Just wanting to know if it's beneficial at all
