I completely agree with @HolyMolyAnne and @CloudywMeatballs - and like them I've lived here for 20+ years.
Im in the Midwest, actually close to a city that has undergone some serious civil unrest in the last few years, I still wouldn't move back to the UK with my kids. I live in a walkable, first ring suburb. Within a half mile radius of my house there are 3 parks, 2 grocery stores, bookstore, drugstore, dog groomer, etc. We walk everywhere.
Guns - other than in the holster of the neighborhood police (who came to our annual block party) I've never seen one. Not minimizing the horror of gun crime, but the idea that everyone walks round armed to the teeth, and I'm at risk of a random house invasion by gun-toting men - madness.
Education - key difference between US and UK is breadth vs. depth. UK forces kids to specialize earlier - I.e. choosing three specialisms at 16 for A Level. Having to determine your undergraduate major before you've even had a single lecture. Breadth of education here is that you can take a little bit of everything in your first year or two before deciding where your interests lie. I actually think that's a good thing.
Recreation - school districts and park systems have programs running year round. Whether it's coding, volleyball or D&D there's something available.
Healthcare - we've unfortunately experienced both physical and mental health issues within our family. Without exception our treatment has been comprehensive and swift. I was admitted to an inpatient postpartum program within 10 days of first going to my doctor. Communication is modern; none of this "wait for your letter in the mail" nonsense, and you can select and self-refer to a specialist rather than overwhelming the local GP with a request to send you on to someone else. I've had three children here, in a (gasp) county hospital and my treatment was exceptional. Private room as standard. By contrast I've seen how much the NHS struggles as my parents age. Appointments missed and then cancelled because the letters don't arrive, etc. The poor standards and inefficiencies of the NHS are scarier than gun crime to me, I can tell you.
These anti-American posts are both tiresome and amusing, actually, as they just highlight how ignorant and ill-informed people are.
Though Europe is a trek, I'll give you that.
