He had more raw Force energy than Vitiate by DE. He could stop himself from aging but was more concerned with having spare bodies in case his gets eradicated like what happened to Vitiate and Plagueis. Vitiate did cause a vortex with his drain essence ritual but Sidious and Plagueis altered the balance of the Force, then Sidious consumed Plageuis' nexus and diminished the entire Jedi order's ability to use the Force. That is a massive severing of the Force, the balance tipped to the Dark, which was what made Sidious so strong, able to beat Yoda, almost break Windu's saber with FL, and what caused that burst of energy when he died on the Death Star II.
Dying made him stronger, and he performed alchemical experiments on Byss involving mass essence drain of its inhabitants. He could have rounded a few hundred of his dark side adepts and used their essences to jump start a genocide that would increase his powers at the expense of Byss' population, he could have just remained content with Midi-chlorian manipulation, but he wanted to increase his subjects on Byss and keep them weak, he wanted to be able to come back even after death which midi-chlorian manipulation alone would be useless in. However, he did use essence drain and claimed that midi-chlorian manipulation was must useful in creating his Chrysalides. He was very much a patron of the arcane arts, he had knowledge of all kinds of sects and studied them for decades upon decades. He created Dark Side wormholes, vortexes that spewed enough energy to rip apart Super Star Destroyers and planets, to hide entire fleets in, to teleport Luke from the surface of Byss into an orbiting Wookiee prison ship.
By DE, Emperor Palpatine was more powerful than Darth Nihilus and Lord Vitiate.

I get that everyone is entitled to an opinion but the hypocrisy is amazing. Believe what you want but you are the last person on this planet that can complain about about
A) being a fanboy
B) unnecessarily hyping feats (or in your case unnecessarily hyping descriptions in lieu to a LACK of feats)
C) calling out writers because they don't share YOUR biased view.
Like believe what you want, but there's no fvcking way you don't see that you do the same exact thing you're calling out people on with regards to TOR characters. There's no point in trying to refute that either.
Sidious can tear the fabric of space itself. Universal level power there.

These things and more."
