You are happy with the handling and performance? I definitely do not rate either of those highly, but this is not the reason to buy these cars in the first place IMO.
I have a GLXR and the thing handles like a boat and is ridiculously unpredictable in 2wd mode on slightly slippery surfaces, but as I said, did not expect this car to rate high up in those departments anyway.
Maybe the club cab might handle a bit better and perform better due to its weight saving over the GLXR? I don't know.
