I'm a native English speaker (well...the Scottish version) and I have pretty strong French, however the place where I felt the people were speaking the closest thing to English I've heard was in The Netherlands.
It's true that the 100 or so most important words in English are still Germanic, and also that all European languages imported tens of thousands of rare, fancy, words from Greek, Latin and French. But I am talking about the middle-space, those few thousands of common-but-not-ubiquitous words that fill a student's vocab list.
In most Germanic languages that stuff is still largely Germanic, but in English it is much more mixed.
