Ren.Bloom dear, you forgot the Greek Tsifteteli. It is not as complex and artistic like the other styles, since it is more a social/folklore than a stage dance, but it is a style on it's own. If you want to see how traditional Greek Tsifteteli (well, in a form adapted for the stage) looks and sounds like have a look at my Tsifteteli video:
By the way, my favorite styles are the Egyptian (especially the modern classical one), the Lebanese, ME folklore styles and of course the Greek Tsifteteli, with which I've been brought up
