I haven't mearured it against other planes but its just cramped in every vector. The FMS bumps into a sharp 90 degree angle right where your knee goes. The sides have thick paneling/ventillation covers so you get no relief there either. The top is a low pitched overhead with tons of things that stick out. The round trim wheel by your knee spins at 40,000 RPM as well, so what little room you have there has to be buffered a little extra.

And the worse part is there's just no room behind the seat. So you can scoot back one notch OR recline one notch, but not both.

That's really the only negative and once you're in the seat its not too bad.
