It could be just me but I just don't like it when I click on a link and I have some idea where it will take be but instead I am being redirected to another url. Customers may not know if that page should be category or product but they can see what the link url is and what the final url is. They may not care though or not pay attention to this. I do
It's like I ask you to show me all products from "kits" section but you instead of saying "there is the section and we have one product available" you are saying - this is the product from the "kits" section.
Also if I browse the store and see all cats pages with products but then click on particular one and instead of cat page with product(s) I see product details page I may think something is wrong there - why this link which should be like the others in the menu follows different path...
Again - this is me. If this approach works for you and converts that is the important thing right
