Getting sick of blowing cheap servo gears!

Yeah that's basically it. The one other main reason for using an external BEC would be if you want to run more cells than the ESC's internal BEC can handle (people used to do this to run 4s on the Mamba Max), but that's a separate issue from running one to get higher voltage for servos.

another vote for the 9100t. I have one in the e-revo, and a pair of 9100s in a e-lst. They toss both trucks around like a rag doll. Very fast, center perfect, have been very pleased.
