Sidious was stated to be capable of taking apart the Imperial Palace, a superior showing to taking apart the Byss castle.
Yeah, manipulating a Dovin Bassal, before gaining a substantial amount of power, is totally superior to possibly bringing down palace. 👆
Not to mention, Luke was far from his prime collapsed, recreated, then destroyed, the mountain size structure, anyway. Scale it, and it's > Palpatine not-so-infallible quote on his TK.
Sidious has access to far more destructive force powers like forcestorms
Luke isn't a DS, so of course he wouldn't have any destructive powers like that in his repertoire.
That being said, if Luke's n00bs trainee Jedi could create something similar to a Force Storm like Skywalker mused in Dark Apprentice, I don't see why Luke couldn't if he actually tries.
generally is generally far more knowledgable in the Force along
Nah, LMAO. Luke has shown abilities Palpatine couldn't dream of. Show me Palpatine using Art of Small, Fold Space, Flow Walk, Alter Environment, doppelganger, invisibility, etc.
with having better TP
Debatable. Luke creating an illusion only Caedus can see --- the same Caedus that no sold Thul TP in a weaker state --- is just as good as anything Sidious has done.
and lightning.
Luke doesn't even use lightning, KEK. Not like it matters, Force Light and Electric Judgement, more than make up for this. As well as his far superior defensive showings.
Given Caedus hasn't even demonstrated force feats on par with Vader
Caedus deflecting/shielding himself from turbolsaers is just as good, if not better, than anything Vader has done in the Force. He has also ragdolled X-Wings, tossed around shuttles, and choked Jaina --- the same Jaina --- that was manipulating aircrafts while they carried tons of cargo, against their will, before becoming more powerful.
His mastery, versatility, and knowledge in the Force, clearly supersedes him however, and that's not debatable.
But even if you are correct (which, you aren't), the ease at which he performed the feat, would still mean he could do the same to Galen, just with more effort. Unless you think there is a massive difference between Jacen and Galen, which, is down right cancer.
