According to your logic, a 1 turn move would be the best wushu move ever.
Do you know that hitting uke in the first turn is actually possible in wushu?
But that sucks. It's not a matter of turns or numbers, your kick could even hit at 350 ed, your opponent could just move laterally or block it and come back later.
You are testing which method suits you better. You can't say it is generally better.
The advantage in 3 turn moves is that you have an additional turn to react to what your opponent is doing before attacking. If you don't take use of that it is your own fault. I'm no frequent wushu player but most 3 turn moves I saw have different variations. You can change from a punch to a kick, aim high or low and so on. You are more flexible.
