It means she's more in depth and her character has been more explored. That has nothing to do with how "good" they are.
1. Congratulations, you posted a match that has Tifa losing in singles combat. I've seen that fight like, twenty times.
Based on the on screen evidence, Tifa loses in a one vs one scenario. Yes, it's impressive, but the fact that Loz was toying with her for a majority of the fight and pretty much takes her out with two hits doesn't build a fantastic strong case as to how Tifa is stronger than Hitomi.
2. You seemed pretty quick to pass judgment on me, I was only returning the favor and 'speculating' an opinion. I'm not under rating any of the FF7 characters. In fact, if you read a lot of my posts you'd actually see that I go out of my way to state that I don't think they're weak. I think Tifa is out of her element in singles combat, and yes I do believe Hitomi is capable of beating her, but never do I say 'Tifa is a weak character.'
This scenario is heavily titled in Hitomi's favor - it isn't a knock on Tifa that she loses. Hitomi is by no means a weak character, losing to her isn't that unimaginable or at least shouldn't be. Tifa just struggles in singles environments, which is something that continues to be over looked.
I'm not discussing anything related to the universes since it's not especially relevant to this match up. If you're just going to say 'FF world is more powerful then DOA world" then that's your opinion - however, as stated before, it doesn't really have much of an implication on this match. It's literally just two martial artists squaring off, which takes a lot of any edge the FF world has away. The characters in DOA take a lot of insane bumps of their own - falling off bridges, waterfalls, etc. Grabbing onto a wall doesn't seem that fantastic in comparison.
3. Ya-huh.
Tifa pretty much gets taken out in one or two hits from Loz. Not to mention, she ultimately loses the fight. The whole fight with Loz isn't really a strong point for Tifa in this match, since all it does is discredit her ability to get the job done one on one. At least Hitomi's managed to beat several highly regarded DOA characters.
You're making speculation about the speeds that the fight are occurring at. Lets face it - we don't know how fast she was or wasn't going, and to compare an unknown to an unknown isn't a great argument for either side.
She 'manhandled' Loz because, as pointed out earlier, he wasn't taking her seriously for a majority of the fight. Hitomi also combats physically stronger opponents and comes out victorious as well.
I'm glad that Tifa can throw Cloud. Again, you're speculating about the speed.
All you've really shown was that a) Tifa is super strong and b) Tifa still sucks at one on ones. Physically, Hitomi is pretty impressive herself. Even if Tifa is physically stronger, which I still do not believe is the case, Hitomi's got the experience and success advantage heading into this match.
Do I have youtube videos of Hitomi shattering benches? No, I can't say as I do. However, Hitomi's defeated opponents who have some impressive feats of there own (Hayate). Therefore, she's clearly a capable fighter.
You seem to be repeating yourself from here on in. You're not looking at this objectively. All these 'feats' Tifa supposedly has, yet she always comes up short in singles combat. That to me tells more of a story than anything.
Your argument isn't especially credible either, I hate to point that out to you. You're entire argument is that "Tifa's stronger because I have a video that says so and the FF world is stronger and blah blah" isn't factoring the rest of the scenario. Looking at the people Hitomi's beaten should be evidence enough that she could handle Tifa, regardless of whether or not we see it. She's beaten Lei Fang, Jann Lee, and Hayate - which is more than we've ever seen Tifa accomplish on her own.
Tifa doesn't have materia access
Tifa has never won singles fights
Hitomi's more experienced
Hitomi is a better fighter
Hitomi's actually won one on ones
Hitomi is one of the strongest Dead or Alive fighters
I just can't get over the fact Tifa hasn't won a singles match against anyone. That to me is a huge sticking point. She could have the power advantage, but at the end of the day I don't see her defeating someone of Hitomi's caliber.
Hitomi's one on one feats are better, she's a more successful fighter, and she's less gimped by the scenario. Physically she's proven herself against Hayate and others in the DOA universe, and while it may not be on youtube, is one very powerful chick.
