I would take the froyo on the other galaxy s phones as a benchmark with a grain of salt. A lot of it is hacked together kernels and os that produces a pretty good product but is not neccesarily indicative of what the actual release froyo will be. And yes flash lags on 2.2 regardless of the phone.
Some of the froyo roms for captivate/vibrant/i9000 etc also do not have voodoo ported yet, so there is lag as they are running hacked 2.1/2.2 kernels in many cases with no voodoo from what ive read.
Froyo will not be the salvation everyone hopes for i dont think but we will see real tangible gains in stability, speed, and everyday performance especially with voodoo which should be ready for 2.2 fairly soon and out of beta and then hopefully ported for us by the great guys at xda.

yeah having used all of verizons "big 3" extensively i think its a testament to the fascinate that its my everyday phone. I will preface that by saying if you dont EVER at all plan to root/rom, etc then the dx is the most polished of the bunch of out of the box. That being said, screw motorola.
The dx may have 2.2 overclock now and stuff but I wouldnt go back even if i could. The htc incredible is a great little phone. I say little because you really notice the difference in screen size. To me the fascinate "looks" and plays like a bigger device and imo i can barely tell the difference in real estate between that and the dx. With the inc, it feels like a much smaller phone and i find myslef (at times) squinting to read stuff or hold the phone much closer to me.
It is however very polished at this point with dozens of roms and kernels, and despite being out for nearly 6 months at this point has a very active dev community and will for the near future.
Still a 2.1 fascinate with voodoo is just really, really fast. Ive said before, and i ll stick by it that its fast than 2.2 x is now (although i cant speak to the oc) I would say hands down that when we get froyo and 1.2 + voodoo for it it ll slay the x outright.
Also, on the gaming topic the incredible doesnt play games very well. It cannot handle baseball superstars at all without massive lag even on an aosp rom at 1.19. Stock incredibles can barely (or can they at all?) play angry birds. So take that with what you will.
Theres nothing wrong with getting an incredible and I'm jealous that my wife is using mine now or id be tinkering with it and flashing stuff now
But the fascinate is the way to go (as long as you use an alternate launcher besides touchwiz). And at some point YOU WILL WANT VOODOO. But hey no pressure
