Orca RX2 or Nosram Pure Evo 6.5T?

[kaszal]

I'm looking for a new 6.5T and can get the above motors for around £50.

The RX2 seems a better deal because there's more discount but which motor is better? I've heard the Nosram is more prone to overheating but it looks like it has the more modern can design. I want to run it with a Speed Passion LPF. Any idea of the recommended FDR ratio for either in 4wd off-road?

Any tips welcome. Thanks.
