Page or Post for Product Review

I am new to blogging and am trying to figure out if a product review makes more sense as a Post or a Page?

I want to be able to group all of my reviews together, so it would make sense to make them posts under the same category.

But at the same time these reviews will be used to affiliate marketing purposes so they need to be Evergreen and not part of any timeline.

What is the general approach to this?
