All kinds. I honestly haven't found a form of coffee I haven't loved ... except for the stuff they disguise under layers of whipped cream and flavored syrup. So that includes Turkish coffee, Italian espresso, filter-drip coffee, South Indian Madras-style coffee, Vietnamese coffee (though the condensed milk gets way too sweet for me), Cuban coffee, Ethiopian coffee served from a jabena...
I haven't spent enough time in the Arab world to appreciate the many variances and hospitalities inherent there, and you can't get more "coffee" than that. Hence why I'm really looking forward to a coffee with you in Cairo someday.
