Obi-Wan faced off against Darth Vader four times and physically beat him twice while beating him through his Force development in a third fight. Obi-Wan Kenobi had the high ground that led to Vader's disfigurement and becoming the ultimate Star Wars cyborg.
Marvel's Star Wars: Darth Vader #13 just made it clear that if Darth Vader and Iron Man were ever to clash, the armored Avenger wouldn't just stand a chance against the Sith Lord, but have an incredibly easy way to defeat him - just so long as he employed lethal force.
Vader knew that he could never defeat Palpatine by himself (especially after his master bested him on Exegol as well), which is why he tried to recruit Luke to help overthrow him during the Empire Strikes Back. He may have not been able to overthrow the Emperor, but he could throw him over the railing to save his son.

Obi-Wan Kenobi soundly defeated Vader in Star Wars: Episode III - Revenge of the Sith and Obi-Wan Kenobi, and is easily one of the most powerful Jedi Vader ever faced. Vader and Obi-Wan were similar in swordsmanship and Force-sensitivity, but Vader's hatred of Obi-Wan often caused him to fight irrationally.
The only Sith Lord who actually killed Vader, Darth Sidious kept his apprentice in line for over two decades. His true advantage was Force lightning, a power which would wreak havoc on the suit keeping him alive.

While Obi-Wan Kenobi was frail by the time of Star Wars: A New Hope, he was still stronger with the Force than Darth Vader. The duel between Obi-Wan Kenobi and Darth Vader in Star Wars: A New Hope looks dated by today's standards.
Thor is a way too powerful for Darth Vader, but it is very hard to compare characters from different universes. Most likely Thor will be able to defeat Vader, as he dealt with some villains, who can destroy galaxies. Vader is no match for those, but Thor somehow survived.

Vader's innate talent with the Force would have made him more powerful than Palpatine, if not for Palpatine meddling in his life from a young age.
