The syllabi are, for now, identical. My advice would be:-
- Whichever PPL suits you
- Study once
- Two medicals, but there are examiners who are dual approved so can do that in one go, you just pay twice.
- Hourbuild once
- Find a school with both UK and EASA approvals
- Take two sets of exams (painful, but you only need to study once, as I said)
- Take one flying course
- Do your tests with an examiner with both UK and EASA approvals
Job done, you now have the ability to fly in both the UK and EASAland.
This, of-course, assumes you have the relevant work permissions. If you don't, just train and qualify where you can work.
