Some of those scores are probably not real FICO scores. Depends on where you're getting them. So they could be wildly different, depending on the algorithm of the source.

You'll also notice inquiries don't generally hit all three bureaus, so that can make a difference.

And "never paying late" has very little to do with utilization, since that usually depends on statement balance. (But that would tend to be about the same across all bureaus.)
