:) Hmm, nice question. They both nice and foot print is great.
From my viewpoint, before mods:
MM cons:
-Incorrect caps for above 4S (fixed with Mod)
-Poor heatsinking, especially first gen. pcb. (Improved with Mod)
-software handicap above 3S (LiPo cutoff can be sacrificed to make it operational)
-poor enclosure design, come loose very quick, i.e. improper for ESC mounting. (Not addressed yet)
MM pros:
-great foot print
-nice programming via USB
-very smooth with latest firmware
-30 fet's total with 24 top level, i.e. with heatsink
Tekin cons:
-no built in Caps, but cap provided, below 4S operation (Modded one allows 6S operation)
- poor heatsinking, heatsink missing (Improved dramatically with heatsink)
Tekin pros:
-very nice foot print
-great enclosure design
-native software support above 3-4S LiPo
-haven't checked Tekin's Hotwire interface, yet
-48 fet's total, none

Common cons and pros are omitted.

In theory Tekin ESC, having 48 fets (but dynamic losses come to play later), doesn't need heatsink for currents below 50A @ 4S LiPo maximum, but with proper heatsinking becoming very capable ESC with smallest foot print.
While MM in stock form can be good for similar performance, while with the mod1 can get close to current capacity of Modified Tekin R1Pro.
Both have Linear BEC's, so both need UBEC (or separate receiver pack) above 3S LiPo, meaning red wire need to be pulled out and isolated.

Price wise MM is the winner, but which one is better? I am not sure, I like them both.
