She-Rulk is consistently shown to be stronger than Jen, matching even Greg Pak's powerful "Heart of the Monster" (HoTM) and Worldbreaker versions of Bruce in recent showings.
Jen, meanwhile, is generally portrayed as more or less the equivalent of Thing, historically even substituting for him in many Fantastic Four adventures. Under normal conditions, Thing might have a slight advantage over her ... it's really tough to call.
However, the OP says these people are entering a weightlifting competition. This implies there is some conventional preparation and training for the event. Advantage shifts rapidly and decisively in Jen's favor in that case, as has already been explored previously in her run (She-Hulk #8 or thereabouts, Dan Schott).
Thing gets the nod over Champion. Champion's beating of the Thing and Champion's other opponents was dependent on Champion's possession of the Power Gem of Infinity. Jen beat the crap out of Champion when he was stripped of the gem. When she used it herself, conversely, even though in her purely HUMAN form, NOT as She-Hulk, Jen knocked out the powerful villainess Titania, a standard spar of She-Hulk, and her near equal or perhaps even slight superior in terms of pure strength.
Champion can take Thing's spot if someone has a showing I don't know of where he beats Ben without the gem.
Otherwise he can contend with Thundra for the #4 spot, who herself used to give Ben fits ...
Most of what I've seen from Colossus in the comics is from the 1980s.
Rhino was duking it out with Hulk 'roundabout that era, Colossus was getting served in barroom brawls with the Juggernaut (Cain Marko in his civilian guise in that instance).
I don't know much about Warpath, but the little I've read about him tells me he gave a good account of himself against Jug, which, again, is the complete opposite of Pete against Juggernaut.
I'll accept that Pete may somehow some way have had his strength greatly enhanced since then. The one I remember, however, belongs right where I put him.
This is a weightlifting competition and your scan of Red She Hulk is one displaying her striking power. That's like saying Rampage Jackson would win a World's Strongest Man competition because he can beat up any of the contestants. It don't work that way.
It's a similar situation with your Thundra/Thing scans. That was a fight not a lifting feat.
The She Hulk scan is when she had an amp (by training in Jen Walters form), she's no longer that strong no?
EDIT, these are examples of weightlifting (on panel) :
Doc Samson lifts an entire building from it's foundations and shakes out crooks : (please log in to view the image)
The premise of this thread is that these characters are entering an Olympic style contest, Zop, implying some degree of training for the event.
IF Jen trains for the purpose of seriously competing in an Olympic style contest, as the original poster's 1st post asks us to consider, Jen gets stronger than Thing, simple as that, and stronger by far.
The premise is sound.
The concept is sound.
And comic book history backs it up.
Check out She-Hulk Volume 2, starting around issue #8 or so.
Strongest? As in LIFTING stuff based on on panel evidence? Thing. Followed by Doc Samson or Colossus (this is ignoring the stupidity that is anything published in a She Hulk comic).
