Rakatan Star Destroyers vs Imperial Star Destroyers
"When the Sith were led by Darth Revan and Darth Malak, the Sith armies used the ancient Star Forge to create a fleet of warships that rivaled modern Star Destroyers in size and power."

Funnily enough, Malak's ship was causing comparable level of explosions via, lazers to the 200GT quote for Star destroyer turbo lazers. While razing taris.
They are angry because they have been forced to recognize that their hour has arrived; that the time has come to surrender power to Shimrra and the new order."
I think this was in reference to the type of ships the Leviathan was, originally they were intended to be Rakatan war ships but later were retconnd to be Interdictors. An Interdictor does rival a a Victory Class Star destroyer in firepower and have the benefit of pulling ships out of hyperspace.

I figure you have a source? Because no source I've read states an Interdictor rivals a Victory, unless I'm missing a source that details the Interdictor. Every time I ask, I never get any source.
It doesn't even seem logical, since Interdictor SD is just Imperial-I with some weaponry removed, and gravity well projectors put in its place, lol.

If I get the chance I'll go to my local book store and take a pic of thw source Wookipedia cites for that claim.

Under the class system, it wouldn't be classed as a Star Destroyer, it's a heavy cruiser according to the Anaxes War College System. Though the Interdictor-class Star Destroyer built by Kuat is indeed a Star Destroyer.
As far as the quote goes in the OP, if it's going off that system, then the only cruiser of the Kotor era at the time that would be classed as a Star Destroyer as far as size goes, would be the Centurion class.
A Star Destroyer size is from 1,000 to 2,000 meters.
A Centurion is sitting at 1,200 meters.
Now that quote doesn't specify any one Destroyer, there are multiple Destroyers in both size and weaponry.
So yes, the Centurion class does rival a Star Destroyer, that said however it doesn't do both. On one hand, it does outsize certain Destroyers but has fewer weapons. Even moreso it's outsized and outgunned from the majority of Destroyers seen.
So therefore, that quote isn't saying it rivals any one type of Destroyer, instead it's just in that class range and has firepower of a Destroyer.
That's the most logical sense I can make out of it.
