Google Adwords - Landing Page Experience

Does anyone have an understanding of how Google rate the Landing Page Experience?

I have a website, with two pages for two similar products. They use the same website template, have a similar amount of information and text. Yet one is rated higher than the other, and I can't seem to work out why.

Search Keyword: Corflute Signs
Product Title: Corflute Signs
URL: https://www.ink.com.au/product/corflute-signs/
Landing Page Experience: Above Average
