Oh come on... this is so biased against Superman.. you are only citing the fight against Doomsday as an example and assume Superman only resorts to fisticuffs. There are so many occasions where Superman allows himself to be beat (especially if it means saving someone else). Clark values all other lives above him.

Yes.. Thor also has altruism in his blood but you normally associate him going into battle without much thinking.. nowadays, especially recently Thor is written as being smart and wise (not just depending on his overwhelming power) which to me makes him a better character. Superman on the other hand has from the beginning was fighting for justice..

That list is somewhat incorrect. Professor X showed telepathic powers against Wanda in Dr Strange: MOM and Azazel showed teleporation in Deadpool/Wolverine. Both movies are released in MCU.

You are conflating comicbook Thanos with MCU Thanos. MCU Thanos even with the Infinity Gauntlet was limited. That Thanos couldn't use all the Infinity stones in unison multiple times without causing severe damage to himself. He could only use it twice in the movies and was severely crippled at the start of Endgame. Even Hulk couldn't use his arm when he snapped to bring all those people back.

Infinity Ultron (in What If) on the other hand showed how powerful one can be if they could use the Infinty gems in unison if they had a body which can withstand the rigors of using the all the gems.

All in all, beings like Galactus, Celestials etc are beyond the powers of an Infinity Gauntlet MCU Thanos..
