On the instant cameras, Kodak would refund the purchase price or you could get a top of the line regular Kodak 35mm camera as a replacement or one share of Kodak stock. So 25 years later, what was the best option?

The technology was not the same and the patent attorneys at EK were pretty good at vetting an application. IIRC, the infringement decision did not turn on the technical merits of the product. It was more about the idea of instant photography.
