Product Page - Use a Drop Down / Product Selection... or use Individual Product Pages?

I have a product model that has 5 options. Now, it’s not like a T-shirt that is S-XXL… but a rather large kit… and each product option / upgrade contains several product items in itself.

For the best (and accurate) SEO performance, should I list the product with a drop down menu -

PRODUCT PAGE- (Drop Down Menu)
Option 1
Option 2
Option 3
Option 4
Option 5

Or… Should each product have its own product page (no drop down menu) -

PRODUCT PAGE - Option 1
PRODUCT PAGE - Option 2
PRODUCT PAGE - Option 3
PRODUCT PAGE - Option 4
PRODUCT PAGE - Option 5

I’m leaning towards the single product page w/ a drop down menu (my rational is more keywords will be on the drop down product page vs spacing keywords out over several product pages) - but I want to ask the Webflow Gurus before I begin.

Thanking you in Advance!
