GT5 for me, just hope it has a more original feel than GT4 had.

 This is pure opinion but my guess would be that to get damage in the game they have to pay the auto makers a fair amount more money for the license then if they have no damage. Mix that with 800+ cars and that could get quite expensive. This could be the reason forza has less cars.

Compare how? number of cars, graphics, car feel, car upgradeability, game progression, overall fun? IMO forza 1 beats GT3 and 4 in everyone of those but number of cars. Don't get me wrong I bought my ps2 just to play GT3 and I loved every min of it. But when forza 1 came out it raised the bar for racing sims on consoles and GT4 fell short. I hope as much as any of you that GT5 is going to be the amazing experience they are promising, but after GT4 and GTHD Im not going to get my hopes up to high.

I just want to say something about the "floaty" feel in GT4 -- a lot of the less expensive cars are supposed to be "floaty" because that's how they actually handle in real life.  As you upgrade your car's suspension or obtain race cars, the response rate quickens.  The race cars in GT4 are anything but floaty, their responses are razor sharp.

um forza is good but GT5 is and will always be better..... sorry sales just prove it every time....

Sales dont mean a game is better...

GT5!!!

Forza just doesnt compare to GT irrespective of which has the more realistic feel.

So you're saying that slightly unrealistic damage is more arcadey and no damage at all?

Yes.  If you can get into a 100 mph head-on collision and drive away, it feels just as fake whether your car looks damaged or not.
