What’s better and what’s worse about living in the UK after living in the U.S.?

Hi! So given the current political climate (or everything climate) in the U.S., I’m considering a move to the UK might be in my future. I have dual citizenship via a parent, so that part is settled. I’ve visited quite a few times in my life and I’ve always loved my time there, but never stayed longer than two weeks.

I’m curious about people’s experiences, how you’ve felt about leaving the U.S., what’s harder, what’s easier, etc.

And if you have any specific experience with the following would be curious about that too:
• Relocating to the UK with your dog (not a bully breed)
• Rent prices vs. buying a house
• Moving a small business to the UK
• Any experience with chronic health/auto-immune conditions clearing up after making the move (have heard stories about this happening from people I know because of the food quality and probably reduction in stress)
