Have you considered using VARIANTS and selling these related items on a single product detail page?

The items are similar -- but one has more features. You are using a CATEGORY page for 2 items that can be better served as a single product page with 2 variants.

Using variants permits BOTH products to receive the google final destination link, and you can offer the customer a side-by-side comparison of the two items, and they simply choose the one they want.

Think about it -- if this wee your brick & mortar store, would you merchandise these products in separate areas? Of course not. They need to be side by side. Some customer will choose to pay the premium for more features. Some customers will select the basic model.

WHAT I WOULD DO:

lose the category. make a 301 redirect from the original category page to the NEW product detail page

I took a look at your site, and it appears that you use lots of categories, and to me, that's a LOT of clicking to find what I want. Your site is a PRIME candidate for advanced search and filtering. But that's off topic.

Think about how your customer wants to shop. Build your store to behave like your customer's expectations. Unless you can change your customers, you have no other choice.

I hope this helps.
