There's of course a difference between 800 speed and kicking ability. Jakob can run a last 200 of 26-27 off of paces fast/slow because he is so aerobically strong and capable of cruising at 3:29-3:31 pace. In the first race you linked he ran the shortest line and looked the sharpest athlete, probably because unlike the others his sharpness isn't as reliant on speedwork/race pace stuff (he does threshold/hills all year long). In the Olympic Final, everyone was stretched out as far as how fast they could go, running lifetime PBs while Jakob was within his abilities and able to close hard (and set his PB).
All this being said, Jakob doesn't profile as a 1:44 guy or capable of running 48 for the 400m. But he's fast in races where the pace is pushed because the 48/1:44 types aren't able to get into a full sprint in a 3:28-3:31 race. So while technically he is a slow, dominant athlete he more than makes up for this in his ability to handle a fast pace. What we haven't seen is if he can take the pace from either the gun or a long way out (a la El G) and win that way. Last year, Tim did him a huge favor by pushing the pace for him. At World Indoors, Tefera keyed off him (though COVID might've factored).
On the other end of the spectrum you have Tim Cheruiyot. While he is a "fast" 1500 guy, he doesn't have a superior kick either. That's why he either runs away from the field or in his best pre-injury races he would slowly ramp up the pace the last lap and then lay it down hard but not explosively fast the last 100 meters (13.1-3 splits). How does he do that while being aerobically weaker than Jakob and many of his rivals? He can handle a super-fast early pace (54pt), regather and rest in the middle and then re-accelerate while the other athletes (including Jakob until last year) wouldn't have an explosive finish left to outkick him.
