Keep in mind that school choice is an individual decision. What works for you may not work for others. And you haven't really told me anything about yourself - what you do for a living, your educational background, what your goals are, and so forth. You've painted some broad strokes and asking some broad questions for which there isn't much I can respond to.
There are significant differences between executive programs vs regular full-time programs. I suggest you do more research on that (you can find the differences on any b-school website that offers both). You should be able to get a sense for which one is more appropriate to your own individual needs and goals after doing some reading.
As for the US vs. UK, you want to go to the school where you expect to settle down. Go to a US school if you're planning on working in the US. Go to a UK school if you're planning on working in the EU. And if you're "open to anything", keep in mind that there's a difference between being "open minded without any preference" and being "open minded with preference". The former is a migrant worker. The latter is a business professional.
