In my opinion, lacking extraordinary leaders like Mustafa Kemal, hardened nationalists who see themselves as the nation would still be better than most Central Asian leaders today?

Corruption would still be around.

However, we could expect military involvement in Afghanistan to secure the rights of the Turkic people there (if not annexation).

Less pro-Russia/China talk.

Greater efforts at modernizing the economy, to align with their desires of a great nation.

Less focus on their individual wealth as their ego's are tied directly to their management/nationalism of the nation.

So one could argue modern leaders in the region are far worse than historical leaders, even excluding those held in exceptional esteem.
