the only advertised number that I pay attention to is the price. everything else should be taken from a review.
a good example of this could be comparing my 1600lumen Epson to the 1300 lumen jvc that replaced it.
would ya believe the jvc was the brighter one, by far?
if you read the reviews, the calibrated brightness for the jvc is closer to 700lumens, and the Epson closer to 400. that's something you couldn't find on the spec sheet. contrast is equally difficult, maybe even more difficult to compare. the Epson relies on a dynamic iris. one that's so clumsy and loud I find it unusable. with the DI, the claimed CR for the Epson was 10,000:1. that's not half bad actually, but I'm sure it got nowhere near that. and they almost never post the ansi contrast ratios either. you really need both on/off and ansi numbers to get the full story.
here's another comparison between the jvc and Epson. jvc rated at 50,000:1, so no surprise it's better than the Epson's 10,000:1 in this case. but from reviews, the jvc seems to compete with and beat many that are rated at 100,000:1 or more.
as for comparing specs from projectors to plasmas. that's pretty tough too. from my experience, it seems as though plasmas seem to have much better ansi contrast, but projectors can have better on/off contrast. a 'fade to black' on the jvc destroys the same scene on my f8500. but something with a few bright spots over a dark image 'pop' more on a plasma. see the scene here:
on my plasma, the scene looks really impressive. it's got so much contrast, that my camera(canon t3i) can't capture the details in both the dark and bright areas at the same time. when I try to take photos it ends up looking bad. my projector on the other hand, still looks good, but since it doesn't have the same ansi contrast, the image doesn't quite pop as much, and my camera seems to be able to handle nearly the full range of the image.
I'm not sure it'll show what I want, but here's a comparison:
basically, when shopping for a display, it's important to consider professional reviews, user reviews, and your personal observations. I usually like to read the pro reviews and user reviews first. that way if there's one or two common concerns I know what to look for, as some times you can miss things in the store. unfortunately with projectors, you often don't get to have any personal observations, so the reviews become even more important.
