True but my experience they are all within the same range. If you get "good" score on one of them, you'd get the same on others. They may emphasize slightly different things but there's not that much difference. Also, nobody really checks that score with a point accuracy - there are ranges, but I'd be very surprised if the difference within range, say 750 to 765, means too much.

Yeah, they are usually are similar. The thing is, for many underwriters, if you ate even 1 point below their range on even one report, you will be rejected. Usually there are things most consumers can do to boost their score by a few points, though, reasonably quickly.
