Star Warhammer: Imperium vs Imperials (Fair question for fans of both)

The Empire has 2 Death Stars in canon and a massive star fleet

But the Imperium has WAY more ships and many of those ships can order Exterminatus, which is the cleansing of all life on a planet, but it doesn’t blow up the planet. Unless you were to throw a moon at the planet. Plus, the Imperium has super soldiers that withstand rockets and could rip apart an AT-AT.

A bolter that a Space Marine would have is basically a grande launcher and the lasgun that the billions of guardsmen carry can easily kill you in 1-2 shots if unarmored and not a marine. And considering how weak stormtrooper armor is, it won’t stand a chance against lasgun fire. But blasters can kill a person in one shot if aimed correctly, since they melt the insides of the target.

If the Empire were to appear in the 40k universe, they wouldn’t last long due to how hostile the 40k universe is. If the Imperium were to appear in the SW universe (Canon, not Legends), they could take Coruscant in a few years, decades, centuries or millennia, depending on where they start off and if they were to somehow adopt alien technology, which doesn’t seem likely since the Imperium is very xenophobic but will ally with some factions sometimes.

I like your written explanation, but as far as the meme goes: is it really fair to equate the Imperial Storm Trooper to the Imperium Space Marine?
Wouldn't the Imperial Storm Trooper Corp be more comparable to the Guardsmen?
Or perhaps if you fused the Imperial Stormtrooper Corp with the Imperial Navy and Army (and got the mean) you would get the Guard?
Because the stormies are mooks, but the Space Marines seem to fill in the position of Jedi/Clone commandos.
Sure, I know Stormies work like marines (and infantry), but Stormies are the basic infantry like the Guardsmen. Space Marines are the melee weapon oriented religious warriors (like...Jedi?), and I read that the Space Marines are often used as a scalpel compared to the Imperial Guard used as the sledgehammer.
Although we hear a lot about Space Marine Chapters, from what I get in the grand scheme of things, they are used more like the way the Old Republic used Jedi (or maybe the Jedi fused with the Clone Commandos) than the way the Empire used stormies.

Oh and btw thanks for explaining some cool facts!
