Well, for starters, Spidey fighting all of those guys doesn't mean drawing damage or having a chance in hell to win, he doesn't, so those "feats" are useless, we know the likes of Thor and others mentioned could obliterate Spidey in the blink of an eye if he wanted. It's not a good extrapolation, Thor being able to obliterate the likes of Darth Vader or Darth Maul doesn't mean Spidey stands a chance, he doesn't, Wolverine has also fought Hulk and he's much weaker than Spidey, hell, Daredevil has "fought" the Hulk.
I mean, c'mon, do you think he stands a chance against Silver Surfer? Nah. Maul could very well "fight" all of those you mentioned.
Darth Maul feats aren't that clear as in the comics, As far as strength goes Darth Maul can lift tons as well, speed, he's been able to pursue a speeder on foot, sustain falls of great heights without effort, higher than I've seen Spidey land on his back from, taking explosions directly to the face, even taking several direct hits from blasters won't kill him, hell, cutting him in half won't kill him, reading opponents' moves before they do them, etc etc, all of this of course assisted by the force, which he can use at will, I think his biggest feat is destroying the entire Black Sun all by himself.
Without the force, he once killed a Wampa with his bare hands, by literally ripping its heart out through flesh and bone, again, bare hands. A Wampa. And he's killed way bigger beasts than that.
No, Young Kenobi can land a kick or two, but young Kenobi is still miles above Spidey. Like I said, Spidey is like a young padawan who's a slightly above average fighter, maybe a bit stronger but that's it.
You're severely overhyping Spiderman nearly to Batman level, I know he's a loved character, but seriously, he wouldn't stand a chance.
He fought Juggernnaut, Hulk, Thor, Dr. Doom and Silver Surfer...all of those characters can beat anyone in the SW galaxy
