Well, you gotta figure it'll make the ESC heat up more since braking is "channeling" the power back into the batteries. Channeling is not "all or nothing", there are
degrees of brake force. This means that the ESC is still switching on and off and you get losses from the slew rate of the FETs. If braking
was in fact on-or-off, you wouldn't have these losses and the ESC would heat up less (if at all) - of course that would be quite difficult to control.
And I don't dare say that mech brakes will give longer runtime. After all, it has already been said that ESC brakes are regenerative, so if anything, you
gain runtime. And even if ESC brakes weren't regenerative, you'd still gain a little runtime because of the reduced weight from the lack of brake servo, linkages, pads, disc, etc.
Another advantage, although not technically related to braking, is that ESC brakes also let you have reverse. The only way to get reverse on an mech braking setup I know of is to use a solution where the gears are switched in the tranny.
