Argentina have improved their game a lot in the recent times indeed. Messi is still a big help for the team of course but they have many really skilled players in their squad right now. Their performance in the qualification round for the World Cup has also been mesmerizing. They made Brazil big difficulties in their game there. When it comes to a finale between Argentina and Brazil I must indicate that it would be great. But this would feel like a Copa America finale at the same time.    So I think it would be better to have one of these teams playing against a European team in the finale.
