If I still lived in Europe i'd be looking at Portugal and also Andorra because of the mountains. Anywhere where these is cool community of outdoor lovers, and some tech entrepreneurship sprinkled in for good measure.
US I rate very highly though, apart from a few things. No walkability is a big downside. These massive roads kill all the vibes and so little cycling infrastructure. LA would be sick if had more cycle capacity or a tube, but it doesn't, so it's just car hell. The food is also diabolical here, even the organic stuff is fraudulent and they put bullshit in everything. Your toxin exposure and potential metabolic dysfunction is at much greater risk. I can eat gluten in Europe, can't touch it here. Healthcare, even with Meta paying it for me, still ends up costing me 3000 dollars a year, even as a healthy adult (somehow). I am seriously worried about crashing on a my mountain bike and what that's gonna cost me. The price of everything is just astronomical here in general.
Benefits = amazing people, great mindset. Innovation and winning in the blood here and if you lean into mentality you can be rewarded. It doesnt feel stagnant like Europe can. If you have a good job, life is good and even better if its remote... a full paradise to explore, with every biome and adventure to find. The sports are great and the weather can be amazing if choosing the right spot.
I do question how you seem to prioritize though. I would live in Canada over US if I could. You'd call that place an freedom killing, tax sucking and ideologically fucked i'm sure, which may all be true, but you over exaggerate the implications of day to day living I think. Revelstoke, CA, is simply a better town than anything I found in US. Walkable, cooler, better community, better geography... everything else is secondary. So none of that political nonsense matters. Ok maybe I get taxed more, but so what, life will be better.
