No. His "consistent" feats are just him throwing a few punches around that due to Marvel and DC Scaling Rules no way denotes that he is comparable.
The Thing hasn't just "thrown a few punches around", even when he's portrayed as weaker, he's still somewhat comparable to the Hulk. The fact that he's fought the Hulk
60 times should say something. Even at the Hulk's strongest in World War Hulk, The Thing was still able to
draw blood from him before being overpowered.
The Thing should be scaled from his own feats or direct scaling such as him defeating Low 5-B and 5-B characters in the same issues of those feats. And him surviving a blast from Galactus described as planet-busting.
This is extremely hypocritical. The Thing fought Umbra once and overpowered him with absolute ease in Fantastic Four Vol 1 298, he's an incredibly obscure character. Also, Umbra absolutely tanked this
Small Planet level+ attack with no damage.
Scaling with the Hulk is a mess because he explicitly has a ridiculously variable level of strength.
Even at the Hulk's weakest, he's still half as strong as Abomination, able to fight opponents like Fing Fang Foom and able to withstand hits from Thor and Hercules. There's no reason to downgrade him at all, the Hulk is just as inconsistent as anyone, and it's not due to anger.
Like, do you have any idea how generous 5-B Thing even is? In 99% of the issues he's throwing cars at people and punching through walls. We found a handful of feats from High 6-A to 5-B that can scale to The Thing or belong to The Thing and we're rating him there. But you act like me refusing Thing to be rated as Solar System level makes me the ultimate downplayer.
If you really want to go down that path, then every street-level in Marvel should be
Wall level. Hell, Thor himself should be
Planet level to
Star level, because he's only got a few
Solar System level feats. Hercules' best feat is
producing enough force to push a planet out of orbit.
Half the characters from Marvel and DC don't even have feats as good as the person they scale to. Silk, Miles Morales, Kaine and Spider-Woman have feats nowhere near Spider-Man's current rating. I could go on, but I don't need to. Also, again, The Thing has fought Hulk
60 times in addition to similar foes. There's no need to overcomplicate this.
Maybe most of his feats are Wall level because he holds back as to not hurt anyone, he's
admitted as much himself. This guy actually has a really good
explainatio of it.
No evidence? How about an explicitely 4-B character stomping Thing in the same issue as he does his 4-B feat. How about Thing struggling with things that are a dozen orders of magnitude less potent? How about Thing nearly dying by a blast from Galactus that is not even planetary as described by narration?
Maybe that's because he's, I don't know,
stronger than the Hulk's normal level of power, or because
Solar System level is an extremely wide tier and Gladiator was completely unharmed by the supernova.
