Having been seriously ill in both countries, I'll take the NHS any day.
I lived through them all, but with the bone marrow transplant, I'd either be dead or bankrupt if I'd been in the US, no exaggeration necessary.
In terms of day-to-day stuff, I prefer the UK ways, too. All four GP surgeries I've had in the UK have been great at fitting me in, and raise the alarm when it's needed. In both countries, I'd say I've had 90% great doctors, and the other 10% I'd avoid in future.
