AFAIK, Europe has been using FAI or no nitro fuel for ages. Nitro content is reported to make needle valve settings less critical, smaller engines use it for higher RPM. If no nitro fuel works fine for you, there's no reason to change.
That is because the only two factories that make nitro are in the USA and one of those blew up a few years ago.
I heard that one years ago, but it isn't quite true (at least, not any more):
