There is no better olive oil than local greek one in my experience although what you describe sounds good too. Of course taste is highly subjective, but that simply works the best for me (and I am a visitor to all those countries, no strong emotional attachment to one from my country since we don't grow olives at all, its often shown by folks from southern Europe as you experienced too).

Also rapeseed oil doesn't have all the benefits extra virgin olive oil has but its a healthy choice too. It seems more temperature stable so doesn't burn as easily as EVOO so maybe better for various cooking.
