English or German NAA (National Aviation Authority) are the licences taken in highest regard to other authorities if you say want to go and work elsewhere, personally, take your exams with either of them.
This high regard of licence is only for converted licences pre part66 as all of Europe now has the same standard exams (in theory).
So now you can do your exams in any approved exam centre across Europe or even the world now and apply to any EASA member state for your licence. So in theory you could do your exams in Sweden and apply to the UKCAA for your licence.
However if you are an EASA member state citizen a good excuse might be needed as to why your not applying to your own NAA.
To remove my electrical restriction from my licence I did some exams in other member states and no company will ever know as the licence says nothing about where you did your exams.
Very very few jobs now ask for a particular NAA's licence because of this. There is no way of knowing where you did the exams.
So my advice is do the exams where its cheapest and apply to which ever NAA is quickest and cheapest for issuing.
And if everyone does that the likes of the UKCAA will have to drop their prices and speed up their awful licence/type application turnaround times.
