kontronik jazz 10-32-55/ twist-42 combo

[captain harlock]

I've been squeezing my mind for the last couple of days to decide which setup to get and this is what I have:
1- Kontronik Twist-55/ Schulze U-Force 75
2- Lehner Basic 5300/ Schulze U-Force 75

The problem I'm facing is not with the ESCs, but with the motor instead. The Basic is incredible as I've heard about it so far. The Kontronik Twist is as good and it has a built in heatsink, but probably becauase it has a smaller rotor and not as torqy as the Basic so it was crucial I guess or maybe not. The design of the Twist if you ask me is much better and the -55 provides higher revs than the Basic 5300, but if we look into the popularity of each one, then I guess the Basic 5300 would win easily.
I've no doubt decided to get the U-Force 75, but I have not decided yet wether I want the -55 or the 5300. Help...anyone:P:

Those of you who have tried out the Basic 5300 how fast is the motor compared to a 9-8T brushed motor?
