mamba esc ?'s

why would you buy a mamba monster max esc now that the mamba max pro came out ? isnt the mamba pro capable of everything the max is ? and more ? plus a smaller foot-print ! just wanted to know what every1 else thinks on this ? i have 1 of each but iam in need of a new esc for another 1/8th scale conversion , and iam leaning towards the mmpro because of the smaller foot-print mainly . if some of you more knowledgeable people no more please 411 me, enlighten me please .
