Quark vs. MM 5s setup

[gimpygolden]

Hey all,
I'm changing around some setups to sell off one complete buggy and need some help on choosing what to keep.

I have too choose which way to go for my OFNA GTP It has a Medusa 60mm in it and I run 5s on everything I've got.
My esc choices are the MM or my Quark 125. I like the MM because of all it's awesomeness but kinda worry about running 5s through it all the time in a road car.

On the other side is the Quark which is super smooth and built for this voltage but not really repairable anymore and doesn't have the programmability of the MM.

As for the car being sold that one of these esc's is going in too, it is a MP777 Inferno with an 8xl geared for mid 40's on 5s so either esc is up to that task.

Which would you guys keep for my on road the MM or the Quark 125?
