dude what r u, a mod or something? theres nothing wrong with wikis. the stuff in those links are literally facts, based of evidence from the books.
it literally shows a list of armaments that battlecruisers can have.
They're paraphrased by random people and lack important details/context. If it's a good wiki you should be able to find the source easily as said in the modpost I quoted. Also this is a scan battle, so providing evidence is held to a higher standard, it's not like you can debate close match ups without feats anyways.

Having a list of armaments isn't that important, what those weapons are capable of would likely be what decides the match-up. Here's a list of the Infinity's armaments for reference.
also a bit more info in favour of my argument. space battles in 40k are usually held over much more realistic distances than other sci-fi universes (3-5 hundred thousand kilometres) and 10,000 kilometres is basically a fist fight in 40k space battle terms, where broadsides and boarding missiles are used.
