ESC wise you want to be looking at an LRP Sphere TC or the Nosram Matrix ISTC (same thing, different colour case). The Novak's look pretty good too from what I've seen of them, but seem to run a bit hotter than the LRP/Nosram.
As for motors I would advise you to stay away from the LRP/Nosram's, I have broken more motors than most for some reason (I seem to change motors more than Mr Foot changes cars
) and in my experience the LRP/Nosram motors are very prone to failing. Another thing to consider is how the manufacturer/distributer deals with replacements, again another reason to stay away from LRP in my experience - swapping a Nosram might be different. Getting replacements for the Novaks has been fine
In order of reliability
in my experience - Orion (never had a failure) - Novak (a couple of rotors have had the magnet come unglued) - LRP (one motor stuttering, 2x rotors exploded and ruined the can's - none have been replaced)
YMMV
