Look, I'm not going to argue this with you. I can tell how this will go-how it always goes. Instead, I'll list the facts.
In the original series, Ultraman always, without fail, beat the **** out of his enemy for an extended period of time, wasting a lot of energy doing so, until two minutes had passed and he killed them with a special attack. There are some exceptions, such as with Baltans, and with Gomora (Gomora took advantage of Ultraman's screwing around and got the hell out of dodge) and Zetton (immune to Ultraman's beamage and smart enough not to let him do the spin attack)
However, on the flip side, UltraSeven did NOT screw around. At most he would hit the monster once or twice, but would then immediately go for his special attacks, unless there was a plot reason he did not. If the enemy survived his special attacks, then he would fight them hand to hand. Spoiler alert-that means that every time he got into an extended battle, the enemy in question was about as tough as Zetton, more or less. Especially King Joe.
When you get down to it, it doesn't matter either way.
Ultraman is no less powerful for messing around, no more then Seven is any stronger for cutting to the heart of the matter.
The two were in very different shows. Ultraman was in a show that allowed him to screw around, being a fantasy more then anything, and it was fun to watch. What they were aiming for.
Seven's show was more serious, and through that had more plot per episode, leaving little time for the elaborate fights of Ultraman, except when they could really build them up.
If I had to judge them, I would say Seven is the superior warrior based on a few things.
One, and most important of all else, he does not have a time limit. That makes a HUGE amount of difference when facing enemies as powerful if not more powerful then yourself.
Second, he is a bitch to keep down. To stop Seven, you must do one thing-Kill him. Nothing short of that, or rendering him unable to transform after he goes back to human form, will work. King Joe is tougher and stronger then Seven, and possibly just as fast and agile. None of Seven's abilities work on King Joe.
Regardless, Seven and Joe duked it out for at least an hour in the harbor, possibly longer depending on how long it took the Ultra Garrison to arrive. They were evenly matched-because Seven does not ever give in.
This is almost glorified to the point of insanity in Ultraman Leo. I have only seen the first five or so episodes of Leo, but dear God, they go out of their way to remind you what a badass Seven is.
Just looking at the opening fight-Seven was doing pretty damn well against the two monsters, actually getting the upper hand and would have won had Magma not shown up and violently broken his leg.
Thing about that though-that didn't keep him out of the fight. He got back up, on that broken leg, and continued to fight the two monsters while Leo and Magma squared off. It took Magma destroying the Ultra Eyes to put Seven down-rendering him stuck in human form.
...except all he did was hinder Seven, as from then on the dude just hikes up his pants and kicks ass every freaking episode. If Leo failed against the monster-Dan was there to make it run the **** away. If the monster was out human sized, terrorizing and murdering, he would track the fucker down and stab it in the eye with his cane. If Leo needed training, he'd damn well give it to him.
This is why Seven impresses me so much.
Even outside of his own show, the man is a grade A badass.
It makes sense that his badassery has resulted in Ultraman Leo and Ultraman Zero. Leo through training, Zero through genetics.
....honestly, one of my favorite moments in all of Ultraman is in Ultraman Leo.
Leo's been defeated by a arm bladed monster, and it's now unopposed in its quest to murder everything.
Dan, who is in a plane that honestly is crappier then the VTOLS in Ultraman, grimaces, grips the controls harder, and his theme music blares in as he, using NO POWERS AT ALL, out maneuvers and out fights the monster in the plane, tricking it into shocking itself to oblivion, and making it retreat.
This is the same monster that he earlier fought, without powers, in hand to hand, and soundly forced to retreat due to "StabbedInEye" syndrome. WHILE knocking Leo out so he wouldn't get hurt in the fight. All while being crippled due to beyond broken leg.
This isn't an argument or a debate.
This is why I consider him THE most badass and best Ultra.
And if you didn't read what I wrote, then oh well. You clearly don't like fanboyistic speeches. Can't blame you, but I'll sum it up.
I consider UltraSeven to be the most badass of them all for his acts both as an Ultra and as a human.
Acts that no other has yet reached.
