Juggernaut strength is not unlimited. Marvel says his upper limit is not known (implying there is a limit). And 8th day Juggs was even stronger. Another reason that points that Juggs strength is not unlimited. Most likely, Superman is stronger since it was shown that Juggs was trapped in solid cement and couldn't break out (spiderman trick him) while it is feasible to know that Superman easily could have broken out. So lets just say we don't know what his lifting strength is. But his hitting strength (damage and force of punch) has a limit and can be known (much less than Superman or Thor). The reason he doesn't hit as hard as Superman or Thor is because of his arm speed is much slower. Thus he might be able to push something massive but not able to damage it as much as Superman or Thor can. Thus WW can easily take his punches (even though he will knock her away due to his unstoppability but she will be fine). Plus his fist is bigger, making the punch do even less damage than if it were Superman's size.
Engaging fellow exemplar Stonecuter in a toe-to-toe slugfest,the punches they traded to one another caused earthquakes and was said to be the greatest fury ever unleashed on Earth. --Juggernaut:Eighth Day
Facing the Stranger who'd grown to about 50 feet tall,The Juggernaut lept up and toppled him with one punch --X-Men Forever #6
Stripped to only a fraction of his strength,he still is strong enough to easily choke Rogue with one hand while fending off Colossus with the other. --Marvel Team-Up #150(it was stated in the Marvel Handbook that both Tom and Juggernaut actually had less than a half of The Juggernaut's power as they had assumed)
The Juggernaut nearly drowned the Hulk by forcing Hulk's head underwater. Hulk had to use silt from the riverbed in Juggernaut's eyes to make The Juggernaut release his grip on his neck. --Hulk #402
Despite having suffered a significant power loss,The Juggernaut's diminished might was still enough to lock up with Prime. The Juggernaut is next seen slamming Prime through a wall. --Exiles #4
Tore through a wall 50 times the tensile strength of battleship steel as though it were a "a thin layer of plywood". --Uncanny X-Men #12
Drained of power to the point of emaciation, a sickly Juggernaut was still strong enough to rip off and wield the entire corners of buildings as giant weapons. --Uncanny X-Men #361
Collapsed an entire skyscraper(possibly a World Trade Center tower) with a ram of his shoulder. --Spider-Man #16
After the Hulk had absorbed more radiation making him more powerful than before, The Juggernaut matched him in a direct test of strength. The opposing forces of their grapple threatened to collapse the entire X-Mansion. --World War Hulk😘-Men #3
In a confrontation with Colossus,the first blow Juggernaut connects with ends the fight. Leaving Colossus unconcious when he lands from it. --
Uncanny X-Men #183
The Juggernaut caused the entire X-Mansion to shake and nearly collapse by stomping from all the way at the front gates of the estate. And was said to be using only a fraction of his power to accomplish it. --
Uncanny X-Men #12
sent Thor hurtling across the skies and then through a store wall with a casual backslap. --Thor #411
took the Fantastic Four's Thing down for the count in seconds with just 3 successive blows. Thing would arise,only to fall back down unconscious. --Secret Wars II #7
When fighting an army battalion,The Juggernaut slammed his fists into the ground with such force it created an earthquake that ripped through the entire valley and brought a hill crumbling down on them. --Uncanny X-Men #33
Seeing the success Thor had after he discerned the nature of his power Cain decided that since Mjolnir must be the source of Thor's power that if he got it he would be unbeatable as well as unstoppable. He also was pretty sure that Thor wouldn't give it up willingly so he decides to pick up a stone pillar and beat it out of him(gotta love Juggy's way of doing things). But Cain finds when he goes to lift Mjolnir that he can't even budge it. To him this didn't add up since he knew he was at the very least Thor's equal in strength and Thor lifts it easy. As Mjolnir returned to his hand Thor explains that Mjolnir can only be lifted by those of the right character.
Strength Level:The Juggernaut possesses Class 100 strength,enabling him to lift (press) over 100 tons. The Juggernaut is said to be unstoppable, and the upper limit to his strength is not known. His strength rivals that of the strongest being on Earth,the Incredible Hulk.
I think Marvel would know their characters strength level and based off them he is stronger than Thor and probably stronger than Dc Superman.
