Which's better Egypt or Turkey to visit?

Both counties are worthy to visit. Depends on what you're looking for. In Egypt you'll visit one of the greatest civilizations of the world. In Turkey you'll see the marks of different civilizations and different faiths. In Turkey you'll have more options, you can have a cultural tour or just enjoy yourself, lying on the beach and tasting the great Turkish cusine. Weather is important too, if you're going in this season (summer) I recommend Turkey, it would be better to visit Egypt in September or October.
