Well, given both games aren't out but based on the evidence:
1) GT will pretty easily outsell Forza unless something huge changes between now and release
2) GT will be a better simulator of driving and tuning the car but I take its damage simulation as untested
3) Forza will offer a good balance between simulation and ease of use and have good damage simulation
If you love Forza I'm afraid you need to accept the fact that GT5 is likely to see far superior sales and due to a much larger user base there will be more people backing GT5 than Forza as the best car simulator.
That's life I'm afraid.
Try to be reasonable... its easier than you think...
