Oh absolutely, Greece is light years better than Turkey. First of all because Greece is a European Community member it is much easier to travel from there to just about anywhere in Europe. Ryanair is just one incredible company, Literally pennies on many of their flights!
Because the Currency is the Euro it is so much more stable than the Turkish Lira.
Legal rights and Human Rights in Turkey are a nightmare, heaven help you if you cross the wrong person especially if the police take an "interest" in you at all!
Having lived in both Istanbul and Athens, I would tell you , while the whole world is not a perfect place, you are so much better off in Greece.And the chance of getting out without having to bribe anybody is much much much better in Greece than in Turkey.
