Any time you push a system to its limits, the margin for error gets smaller, so if you want to push the system this way, then mechanical brakes will widen the error margin. If your setup is comfortably within the limits, reliability is not typically an issue. :)

Well I can't argue with real experience since I don't even have a 1/8 controller/motor yet (but I'll argue anyway because I'm an idiot). After reading the debate about battery packs between CC and their customers (Zippy packs) I got the impression that under hard braking there is an increased chance of cooking the esc or puffing the pack.
While I can definitely appreciate the simplicity of running motor brakes both mechanically and aesthetically I feel that mechanical brakes do have benefits:
1) Front and rear bias tuning.
2) Offloads the braking strain from the esc, motor and batteries.
3) Brakes are cheap.
One downside that bothers me especially since I plan on running 6s is that having the extra servo is going to put more strain on the MMM BEC.
