The LRP has only just been released, so don't expect much in the way of feedback. In my opinion, the ESC just looks like an SXX with a fan and some new stickers. Only 4S capable.

The Novak ESC is a little dated now, and the motors don't really come with a useable kV for 1/8 buggies and truggies. Again 4S limit.

The Tekin ESC is good, bearing in mind it hasn't been out that long, and so Tekin haven't been able to iron out all the little problems yet, much like the MMM. The motors, however, I cannot recommend. Yet. I've had a couple of rotor failures. I've got some new things to try (slipperential and gearing up), so I'll reserve judgement until then. 6S capable though! Tekin are really trying to look after anyone with ESC/Rotor failures and are being quite quick with help and advice.

Hobbywing/Speed Passion. I'd just skip past the SP part and just get the Hobbywing stuff - it's the same, but cheaper. This combo is by far the cheapest out of the four. I don't have much experience with the motors other than to say they feel very small. They are only the same diameter as a normal 1/10 motor, just a little longer. 80A Hobbywing is 4S capable - same as the SP, but the 150A HW is 6S capable. Also comes with a quick programming card, which is very easy to use and makes adjustments a breeze. To make use of their warranty, be prepared to send it back to China for extended periods, should anything go wrong.
