There's the old saw about how you pronounce Latin will depend on whether you were taught by Father Brown or Father Leary.

In areas where Catholicism has predominated, it's more likely that the ecclesiastical pronunciation will dominate. As I recall, the German exchange students I had in some of my classics courses used the classical pronounciation (their big weirdness was pronouncing θ as an aspirated t (like in Goethe) rather than a th sound.

As far as I have experienced, the "classical" (i.e. not the Italian-like ecclesiastical) pronunciation differs a lot by native language of the speaker. It was long ago, but I remember having had only very basic pronunciation guidance at my secondary school; we certainly used Dutch vowels (apart from the "u" of course) and the Dutch "v" which is very similar to the English "v". In a context like that academy I would have been understood, but with a very typical Dutch accent.
