Sweden or Italy air free to play?

I'm free to play and have been recommended both the Swedish air tree and the Italian air tree for a short grind. I'm already rank 5 Sweden (I have the SK60B and I'm grinding SL for the SAAB-105G that I finished researching) and rank 3 Italy (SM.92 and P-47), should I stay with Sweden or play Italy more? I want the Gripen because it's my favorite plane but apparently Sweden rank 6 is terrible and hard to get through because the planes are bad, would Italy be a better option to get a Gripen faster because of the Hungarian one or am I far enough along in Sweden that it would be faster to stay with Sweden?
