Even in recruiting they are not anywhere close to being on equal footing.
Fulmer standouts: Peyton Manning, Tee Martin, Al Wilson, Jamal Lewis, Peerless Price, Travis Henry, Travis Stevens, Eric Berry, Deon Grant, Joey Kent, Casey Clausen, Robert Meachem, John Henderson, Charlie Garner, and probably a bunch more I forgot about.
Jones standouts: The only two that come to mind so far are possibly Derek Barnett and Jalen Hurd?
In Fulmer's prime, his teams won a lot of games. For example, I remember 1996 not being considered a big success due to the first half Florida meltdown and the Memphis debacle, but that team still finished 10-2. Now during his later years, when it was obvious Tennessee was falling further and further behind rivals like Alabama and Florida, a change was probably in order. I still don't recall questionable coaching decisions like I'm seeing now though.
Now Jones may very well improve and be a big success. I think we're all pulling for him and would love to see him win big here. And he seems like a good salesman and very likable guy. At this point though it's a little ridiculous to compare the two.
