What nation to grind next?

I have USA, Russia, Germany and China grinded on air except for a few optional planes that I will never use. Im planning on grinding France or Sweden next but Im unsure of what should I grind.

Both are quite fun!
For France, I’m at rank 7 and so far the grind has been a lot of fun. The Ouragan, Mystères, (all of them), Etendard, Mirage III/5 and F-8E are super interesting to play. Do note though, that some of them are considered “mid” and won’t be easy to play, but if you’re fine with that the gameplay can be really enjoyable.
For Sweden, I’m only at rank 6. Not everything has been my cup of tea so far, but I particularly enjoyed the J21A and the J29A

Idk broooooo, France has the mirages and the rafale wich are the main points and sweden has the gripen plus f18 with basically unlimited countermeasures, I want the rafale but I also want the planes with insane countermeassures in sweden, I will probably go for france since every time I face the rafale I assume Im gonna get cooked by the micas wich are at least for me the best missiles in the game but the survibability of sweden is just something else I also want

Italy is calling. The mid tier is so much fun.

Maybe but I wanted to get planes that I dont have at higher rank, for example because I grinded germany i have the typhoon that Italy also has, and if its for the gripen I would rather grind sweden, also im starting to want the drakens and vigens ngl plus i dont particulary like lower brs, altough I saw a lot of people including my friends say that the 9.3 ariete is the best of its br, but thats premium so its another story, im just do indesicive when it comes to selecting things that dont particulary have like considerable cons or pros, but ill think about it
