This was still a Jedi Padawan Kun with a slight darkside amp. Kun at his peak got many times more powerful than this, and was still below many Sith Lords. The easiest way to picture this is:
Jedi Kun <<<< Peak Kun <<< ROTS Sidious << ROTJ Sidious << Dark Empire Sidious < Peak Luke
It might not represent the higher things, but it does show that using "doors" is pretty bullshit against peak Luke. Where you can scale up from here is anyone's guess when it comes to comics, but it's definitely above door level.
Also, Abeloth was one of The Ones, which if you watched the Clone Wars you would have seen them in the Mortis episodes. She was somewhere around the Son/Daughter level and they were required to seal her away. Luke also bounced off her with an attack in the same fight she was stated to be a dozen times stronger in the force than him, so cracking her ribs with an amped punch is pretty good, and at the very least puts him far above Kun in physical strength.
Beskar barely getting scratched >>> Doors that Obi-Wan/Jinn were cutting.
You could get into Vader shit too, but it still doesn't get a great assessment, and I'm sure Dooku likening Anakin's strikes to meteors will be written off. Meh, Luke cuts a few dudes here.
