@amcu: Huh. I'd forgotten most of these aside from the BOTB and White Walker one. Those are actually pretty impressive strength feats. I re-watched the ship fight, and Euron doesn't have any that compare, outside of just appearing ferocious and like a beast in the ship fight against Yara's men.
I guess if we argue a pure feats perspective (and possibly this is just how it is in-universe as well), then Jon should be both stronger and more skilled than Euron. I personally feel that the show is portraying Euron as a physical beast on par with the people I previously listed (Styr, Tormund, a very poor man's Mountain) given his fighting style and personality, but I guess we'll see how they portray him in the rest of season 8.
@amcu: I’d have to rewatch and analyze his fight again. I don’t remember any particularly noteworthy strength feats for Jon either though, and he fights with much more finesse and skill than Euron does (Euron’s style seems similar to that of Tormund and Styr, just overwhelming ferocity and strength, with some level of skill mixed in). One doesn’t usually fight with just raw ferocity if they aren’t physically dominating from what I’ve seen though.
Team 2, solid fight. Jorah loses to everyone here. My respect for Bronn has gone up a lot recently, but I'm not entirely sure how to rate Euron. He seems like a beast, but his best feat currently is beating the sand snakes, the best (arguably at least) of which newby left-handed Jaime was able to fight/match for a prolonged fight. So not sure how impressive that is.
Jon is a beast against fodder, but has lost to the established fighters he's faced (Styr - only defeated due to luckily finding a hammer within arm's reach after being solidly beat up, Tanner - solidly defeated until Tanner got distracted). I can't tell if I'm convinced that the choreography of his fighting/efficiency at killing fodder is enough to convince me that he beats Bronn. Given Jon's performance against Styr, I'm also not entirely convinced that his skill and own physical prowess will be able to overcome the sheer strength, rage, and ferocity that Euron brings.
All in all, I'd say Bronn narrowly beats Jon, or matches him, while Euron beats Jorah. Swap those matchups and generally the same result (Bronn beats Jorah, Jon/Euron more or less match each other or at least have a prolonged fight).
