ESC choice

[safk]

Given the choice and that the price is about the same should I buy a new Hobbywing V2.1 90A or a second hand Tekin RS Pro?
I am a relative novice running a 2WD buggy currently fitted with a 10.5T motor but would like something that will still be suitable as I (hopefully!) improve and go for faster motors.
A reason for choosing one of the other would be useful too please.
