Not sure what joules are required to ko a bull, but stopping a car at 50mph is roughly between 10x below to somewhat above the feat Aragorn scales to.
Abilities wise, it's certainly interesting.
Both can power through or resist pain, but Joe outright ignores it up to a point while Aragorn willpowers through it. Point to Joe.
Aragorn can outright see into his opponents mind while Joe can sense danger. Point to Aragorn.
Aragorn has enhanced senses that allow constang awareness of surroundings and quick reactions such that catching him off guard is very difficult. Joe has instinctive reactions allowing him to react while unconscious or... instinctively... I'd say even (awareness is somewhat required for instinctive action).
Accelerated Development is bad for Aragorn. While it's not the best form of the skill, it's enough to let Joe go from being blitzed to blitzing in a fight. If Aragorn has that 10x AP gap, then he can still get a quick win, but if they're comparable? He needs to clutch hard. Albeit this seems to mostly be a skill and speed thing, though AP does also increase its improvement is far less impressive. The AD is also less effective in this fight for skill as its showings are all in boxing, not against a weapon user.
Aragorn and Joe both have Fear Manip, but both are largely irrelevant albeit in Aragorn's favour. Aragorn can resist and Aragorn's FM is unreliable. It can help, but its appearance is somewhat random.
On the other hand Aragorn can stun Joe in awe if he unveils his full majesty as a royal Dúnedain. Joe will be unable to meet his eyes in the fight and will be briefly stunned.
Perception Manip is an advantage to Joe, but it's countered by telepathy and Aragorn's enhanced senses. Still annoying, but manageable.
Damage boost comes from a counter technique. Deadly if landed, but that's questionable against a telepath with great awareness and reactions. Damage reduction is also reliant on gripping a opponent... not something that easy when the enemy has a (wooden) longsword.
Intelligence goes to Joe... because Aragorn hasn't been touched by intelligence revisions yet. Shame. But he has weapon mastery which lets me counter that.... kinda. It's just two different fields afterall. Aragorn is a one man army above all other skilled mortal warriors in the age. Literally goes untouched and unhurt in all 3 books. But I'll note that if disarmed, that all goes out the window. Aragorn is presumably a fine hand to hand combatant, but against Joe? Yeah...
Aragorn does have a sheath, something that will provide his wooden sword with a great enhancement in durability and reliability as a defense. Afterall, it gives a blade which has been in it invulnerability.
Some extra stuff too. Aragorn has the Palantiri but that is impractical as they need time to focus. Not handy mid duel. The Elessar will heal Aragorn alongside his low regen, but neither have shown combat applicability, albeit the former will save him from mortal wounds. He also just has a bunch of resistances and other stuff that ultimately don't matter in this fight.
