Tekin T8 or Neu 1515 in truggy???

Here's the thread on my MBX5-T - i figure there's probably a lil more traffic through this section, so posted this Q here...

My MBX5-T Conversion

I'm stuck on this one, and really wanna get this motor ordered... I gotta stop thinking, it's doing my head in... Now I am not sure on the motor I should run...
I have 2 motors in mind, but am leaning towards the tekin...

-Tekin T8 2000kv truggy motor
-Neu 1515 2D/F

Is the neu really THAT much better??? Wouldn't mind saving some dollars here, (~USD$60 is a good saving to make!) but I really really need as much runtime as I can get, but they are close enough on paper for me not to be able to figure it out...

I need advice... Which motor do I go for on 4S, the tekin or the neu??
