Okay I know the title is odd, but it's the best way to describe what I want to ask, what, so far in Cannon, are the more important titles (both books & comics) to the Cannon, meaning impactful?
Well, obviously the largest cannons are the most impactful ones. Bigger shells/blasts and all that cause quite a bit more damage. I think the largest cannon we've seen so far in the new canon would be the gun on Starkiller Base, if that counts as a cannon, and it has a nice title to boot.
I've always been fond of the fine styling on de Valliere cannons, like this one. For greatest overall impact in both practical and historical terms, I'd have to do with the iron 32-pounders used by the British Navy. These guns safeguarded British colonization of the Americas and India, and broke apart French fleets on the Glorious First of June, off Cape St. Vincent, and at Trafalgar. There is no British Empire without these cannons, and as such they might be the most impactful of all.
Mortis, Dooku vs. Anakin duel of the week, bombad Jedi, D-Squad and the Shadow Virus. The other stuff are mediocre at best and add nothing to the overall story.
For the love of all that is good and holy, I wish every fandom page on the internet had a disclaimer at the top that explained that "canon" is not spelled "cannon." #1stworldpetpeeves
