The best one single servo setup?

Wonder, what is the absolute best,strongest, digital and (brushless) servo I can buy. It's time to have my E-Maxx 3905 up and running now.

Ignore how much it costs, which servo is absolutely the best on the market.

Here are some suggestions, I looked at:

Are these good and strong

Futaba BLS352 Brushless 3D Heli Servo

Hobbico CS-170 Std Digital Ultra Torq 2BB TG Servo U

DS8711 Ultra Torque Servo by JR

Hitec HS-7955TG V2 Dig High Resolution HT Titanium Gear
