Morgoth's higher end is probably better though it is planetary or what have you. The issue is that Tolken is hard to place via the guy above or on par with moutain sized dragons can be outplayed by a fairly normal (in comparison) elf. Fingolfin was kicking the shit out of Morgoth until he grew tired. Dancing around his attacks.
Imagine a politically amped force user with politically amped speed with a sword that can cut through anything. Even if Morgoth was more powerful, Sheev's force powers should be able to protect him from the esoteric powers.
If it was just a wizard off with no sword slashing, then Morgoth would maybe come out on top. Sidious might have zero skill with a saber, but he's way too fast in close quarters combat for Morgoth. I don't recall any great feats for Morgoth in that respect either.
It'd also be interesting to contrast their higher end powers as well.
There's alot of truth there though. Some people put him far above people like Odin simply because of the part he played in creation and him being a "God". Or because he destroyed the sun and moon in a vision. Both things orbit ME iirc.
It's very possible ME is much like the original thought of how our planet was where everything in the skies is pretty much decoration. Even moreso when you consider the time the books were written.
He does have decent feats though, but not to the level some people put him on. I think his best feats put him at mountain range level over an unexplained period of time. The only way his feats really become huge is if you assume ME is much like our universe now, which makes no sense and I don't think there's anything to support that. Planetary is a pretty safe bet in these types of threads at his height.
Sidious is laughably overrated based off a few feats. From the movies he gets slaughtered by Sauron from the films alone. If it’s the eu these kids are exaggerating it’s the same thing dc fans do which is wank a few feats and try to convince as many numbskulls as possible.
Thanos beats the shit out of Morgoth any way he wants to unlike Sidious. The Sidious fanatics know film versions only that Sauron just wrecks him with one swing of his mace.
Good thing Sidious isn't stuck to only the movies like Sauron then in your example. Nor did he get defeated by a powerless human in the movies at full power.
No Sidious was killed by a one armed Vader without a saber and cackled like a ***** all the way down. The guy had a powerfully magical sword and a lucky swipe. Sauron still wasn’t killed unlike Sidious.
Sauron would make Sidious bend the knee. Glad we had this chat.
