As I am Greek, I 'll probably be a bit prejudiced against the Turks, but I'll try to be as neutral as possible. First of all, the Turks were the military race of Islam, while the Arabs (Egyptians and Persians) were the cultural race. Most Turkish sultans didn't even know to read their holy book, the qum-ran, because they never learned arab, even though they knew how to declare Jihad against Christians...
The Turks jumped out of the steppe a fine morning and decided that their fate, their reason to be, was to conquer the eastern Roman Empire, which ment to become the Empire's imperial race by overthrowing the Greeks who have been the imperial race since the time of emperor Konstantine I.
The truth is that we (the Greeks), have finally got to realize by the end of the 11th century, that being the imperial race is more of a disanvantage than it is a privilege, and that the future belonged to National States, not to empires. The Turks never realized that. They came to Europe in 1453 with horses and carriages, and they left Europe 5 centuries ago with the same horses and carriages... No progress, no nothing.
Fine militants they were, but only militants, their empire cannot even dream to reach the glory of the millenium-lasted Byzantine Empire, the last one to actually deserve the title of the Empire.
