While I'd generally say that the F-35 is probably the best (one of the best) option for countries like my own (Denmark), who need/want a plane that can do a bit of everything, we also need to see what's happening in Ukraine.
If you have a large country and can hide your airfields hundreds of kilometers from the front, the F-16, Rafale, EuroFigther and the F-35 are all fine, but you have more options with the F-35. If you're a small country, like the Baltics, or Denmark, they are a silly choices if you expect to fight a battle at home. You simply don't have anywhere to service the planes after missiles and drones take out your three airfield equipped for the F-35. In those cases the SAAB Gripen is a much better choice. You can service is straight of a highway with basic tools and conscripts. It's also a plane designed to fight Russia, so if that the enemy you expect, it's fine.
