Gotta give us more information. Are you racing them or just bashing? What motors are you running? How much are you willing to spend?
I own 3 Cayote ESC, 1 Crest X, 1 Crest X Evo, and 1 Crest RS 120 and so far I quite like them. They have a very smooth power delivery but the braking power isnt as strong as say Hobbywing ESCs.
