When I've tried to improve at visual design, the hardest part was developing taste. Comparing options side-by-side and articulating why one is better is exactly how you build that skill. The aggregate rankings matter less than the act of judging.
Have you considered adding a "why did you choose this one?" prompt to collect qualitative reasoning alongside the votes?

If I don't belong to one of the markets that the landing page is trying to sell products or services to, I shouldn't be able to vote -- if I vote, I'm just polluting the dataset of what their actual potential customers think of it.
If the two landing pages being compared aren't targeting the same market of potential customers [+], it's unclear what comparing them achieves.
It's unclear if voting on a landing page in this kind of artificial setting is predictive of something more material like how often a potential customer proceeds to sign up for a demo, or pay for something, or call sales.
[+] or given a lot of these are AI landing pages, I guess they're targeting investors.
