I think the reason people say that is because the comparision is flawed. Projectors are almost always set up much larger than flat panels and all else equal the smaller image will always look sharper. It's just the way things work.
How would the best projector on a 90 inch screen fare against the $6000 90'' Sharp Aquos?
Well let's not go for "the best" since well there is no "best", and if there was it would be many times the price of the Sharp (it's probably a close race between the Sim2 Super Lumis, 1080p and the Sony VW1000/1100 which is 4K, both are over $20k, and both are stunning projectors). So lets stick with something reasonable, I found this article:
The way I read it, the picture quality is just OK, and when you get out of the sweet spot it drops off quickly. But they've also got some interesting numbers. They measured contrast from the 80" Sharp at 2700:1, they measured the JVC X30 (quite possibly the best bang for the buck projector out there) at over ten times that, 28,500:1, and that image quality (on the screen they used) doesn't change as you move around the room. On important thing to note is those were both measured by the same reviewer.
If you want to spend more like what the sharp costs on just the projector, there's the JVC X700/RS57 which can double that again. And from what I've seen in my short time demoing an X55 (last year's model) they are definitely sharp/detailed.
