Top 15 European Cities
London, Edinburgh, Prague, Vienna, Berlin, Munich, Amsterdam, Rome, Venice, Copenhagen, Salzberg, Brugge, Paris, Strasbourg & Oslo are 15 that I have visited & don't regret any
Top 3 - Prague, Salzburg & Rome
Only 15??? It's impossible!
To Fiona's list I'd add Barselona, Madrid, Dresden, Berlin, Amsterdam, Venice... I spite of that till now I've never been there... But soon, very soon... 
I'd add Galway, Bristol, Brugge and Lisbon. Would always go back there 
My favorites (in order)--Venice, Munich, Barcelona, Nice, Rome, Paris, Prague, Dublin, Lugano, Salzburg, Florence, Basel, Dresden, Edinburgh, and Berlin.
Enjoy.

Sticking to the countries u're listing here's my reply:
Paris, Nice, Madrid, Barcelona, London, Edinburgh, Dublin, Berlin, Dresden, Zurich, Vienna, Rotterdam, Amsterdam, Bruxelles, Antwerp. This way u'll taste Europe from the eastern flavour of Dresden till the mediterranean atmosphere of Nice.
Not sticking to ur concept of central Europe i'd say:
Paris, Barcelona, Lisbon, Split, London, Berlin, Amsterdam, Edinburgh, Rome, Venice, Istanbul, Prague, Vienna, Copenhagen, Moscow.
