Jeanty is quicker than Judkins, and has superpower-type contact balance. I think Jeanty's a clear-cut tier ahead as a prospect.
I'd project Judkins as a David Montgomery, Najee Harris type of power back. He's strong as all hell, sees the game well, and looks pretty good as a receiver, so I think he's got a high floor. But his hips look REALLY tight, and I don't think he has NFL level breakaway speed. He'll be a low YPC grinder, because he can't rip off the chunk runs to boost his averages.
I think he'll be a successful pro and will earn some good money, but I don't think he'll be anywhere close to Jeanty.
