Not too sure about the situation in Eire, but flying in the UK is completely different to the US. Airspace here is much more congested, restrictions on altitudes, more formal RT.
Weather is a big factor too. Getting used to flying in poorer visibility and lower cloud as opposed CAVOK everyday in states gives you much more confidence.
Navigating using more features which tend to look similar like fields, small towns, minute rivers and rail lines as opposed to the coast of Florida and interstate highways!!
Sure once you have your PPL, take a holiday there to build up some hours and improve your handling. You can do some nice trips and in the US they are (or were when I was there) very GA friendly.
