I guess your final choice depends on what you want to do with the ESC and if you buy it for one specific car.

Budget
2WD / 4WD
Competition or Hobby
Turn limits motor
Voltage range / 2 to 4S
Setup possibilites via USB or other
Forward only or Forward / backward mode
Active cooling or not
Soldering or pre-wired

I have in use the following ESCs in my cars which I can all recommend:

Speedpassion GT 2.0 Pro => a bit big but my favorite for setup, feel etc.
Tekin RS Pro => very small, in use when space is an issue in the car
Novak GTB => a bit big & old style, but I like the super-smooth Novak power regulation feel. I run this in my Cougar.

In the Cougar you can fit most ESCs, but some fit better for installation and cooling (check the wiring scheme in adavnce on pics)

Maybe look into getting a top ESC as used from the oople forum.

Some years ago I would not have bought a used ESC but today I would as some products are really bombproof.
