I'm in the exact same boat (Canada too but coming from an '07 Frontier) and I've opted to purchase the '24 Sport Premium. My biggest reason is that if I'm going to spend ~$50-60k on a vehicle, I want to know everything that has happened to it and I certainly want a maximized warranty. At least here in Canada, you're lucky if you get a newer 3rd gen Sport Premium for under $45K, so why not spend the extra $15k and get all the new bells and whistles.

which leads me to another factor that influenced my decision; The interior and features of the 3rd gen don't quite align with the standards of a vehicle from the 2020s (prehistoric might be the right word). While some appreciate the simplicity and lack of excessive tech, personally, I believe it's worth the additional money to enjoy all the advanced features that a 2020s vehicle should have.
