I'm certainly old enough to remember both scenarios.
Inside the EU is much better for a host of reasons.
With respect, you visit the UK so your view may be more that of a tourist than a resident: you don't pay UK tax, or face the central worries of NHS, schooling, crime & such stresses.
You are welcome to stay in the EU and I am surprised that you and so many expats have not gone down the route of becoming a full citizen of where you live, be it France or Spain.
