Novak GTB or LRP sphere competition?

[xx4 fanatic]

High im going to buy a brushless motor. As of now im going for the Orion Vortex brushless 5.5 or a 6.5, but im waiting untill people try it and there's some reviews of it.

My question is what ESC do you guys suggest since Orion doesn't make one. Right now im leaning towards LRP but i would love to have some other opinions.

Also any opinions on if i should get a different motor then the Orion Vortex and why is welcomed. I havnt owned a brushless motor so any input or advice would be appreciated. (if it helps im running a xx4 atm but im going ot upgrade into a x-5 in the possibly near future)
(i think i should have posted this in electronics. sry don't have many post on oople so far)
