Omega has a lot more AJ than Seth.
Seth feels like big spot after big spot and little selling, Omega on the other hand is a fantastic storyteller and makes every movement mean something. Selling is a lot better than Seths too, I don't know how you consider Rollisn more athletic. Kenny and AJ are both more athletic, Seth since returning looks so much slower nowadays. You can visibly see the gulf between him and AJ in the WWE.
The Kushida-Takahashi match was also pretty good despite some botches, although it's pretty easy to overlook with those two great main events.
It was nice to watching something different which is the Japanese style, but that main-event was basically high spot galore which is funny how Meltzer gave that a 6 yet Cena/AJ at SS a rating lower, the only difference between the two was the match length and the fact that Cena/AJ had more false finishes. Metlzer had been hyping Omega and Okada overly in the lead up to the match, he is most definetly on the NJPW payroll and it's one of those secrets in the bizz for a while now he has lost respect universally given his lack of objectivity which is a shame because he has become a business man who knows how to get reactions out of gullible smarks above the respected journalist he once was.
The other thing I noticed was the Okada/Omega contest diluted the psychology in the ring because they didn't pace the match well and performed repeated stunts, they were stuck in gear 6 throughout; if you watch Nakamura/Styles from last year you'd see that wasn't the case. Ultimately, America is the mecca of pro-wrestling and a global style; if you can get over there you'll truly be able to prove your worth because it's the most challenging place to get over at the main-event level, the market is not limited to one country, but you got to work unique styles across each continent, be excellent in the ring and have a good character. Plus there is no off season, after mania you're back on the road 5-6 days a week; Omega/Okada can afford to be stiff in the ring and take more risks because they're only going to be working that match for the night, after WK it's holiday time for them.
Seth Rollins is a lot more athletic then Omega, his in-ring style from day one has revolved around his fluidity in motion and he grew when it came to his technical prowess. The American style is not meant to be stuck in one gear like in NJPW, Seth varies his pace; it's how you do not dilute psychology in the ring and tell a compelling story and he hasn't lost a step at all as we've seen from his excellent performance at SS.
As it stands Omega is an inferior version of Seth Rollins in that he has a similar in ring style but he lacks fluidity of seth but what I give him credit for is his striking but you put Seth on the same platform and he'd outshine him because Seth has to work a lot safer in America, in Japan you're not limited by what you can do which is dangerous because concussions are a lot more likely but the advantage they have is that their schedule is nothing like the WWE's.
I give credit to Omega for the character he has created for himself, I expected a little better from him on the mic but in Japan you can't really show much. If he truly believes he is a top 5 talent he can only prove that in the WWE, it's a joke to even compare him to the likes of AJ he's more on the Seth Rollins, Roman Reigns, Randy Orton category; the likes of Styles have proved their prowess throughout the 2000's and here in the WWE at the age of 39 he puts in performances which forces Vince to put him in the main-event, a guy like Vince who has seen it all and holds many stereotypical biases about guys the size of AJ was forced to ackowledge his prowess and express regret of not having signed him earlier in many ways reminding him of how shawn made him feel in the 90's, Styles at 39 did what Shawn did when he returned from the back injury in 2002; we all knew he was an ATG but to take it to another level is just unreal.
You marks are an insult to pro-wrestling, mentally inept to the point where Okada/Omega is being rated better then HBK/Taker; if given the same platform which was mania 25 before 70K people I highly doubt they could incite the reactions which HBK/Taker did a) because their characters are weaker and b) because they're just not at that level.
It's good that NJPW is pushing new guys but without a shadow of a doubt in my mind Tanahashi is still their best star, he's the only one I can say for sure that would do well on the main WWE roster from an in-ring point of view. Omega would do well in the upper-mid card unless his mic skills helped him get to the main-event, I can actually see him working the same spot as Seth with the right support both he and Seth are average on the mic but as it stands Omega has a fresher character, from an in-ring point of view Seth is better but Omega will get to his level with more experience or maybe he is there already but it's just that lack of fluidity it's a bit like how John Cena is much improved in the ring with a great move set but remains robotic
