Stipe isn't great. He's a pretty good HW who exploited JDS' bad boxing defense for 2 rounds, then started fading and took some big shots. Jones and Stipe aren't close skill wise.
As a match-up though, JDS' durability, TDD and boxing combinations match up well with Jones' skillset. Jones is a good striker, but his boxing isn't good, and boxing defense is JDS' and Jones' biggest weakness thus far.
Jones would likely win though, his distancing is better and he's the grappling aggressor, meaning JDS would be on the back foot, but without the slick movement of Gus. That power though is a equalizer many a time.
