After a lot of experiment i think there are more diferenz in the flat and slice serves.
For example where to hit the ball and swing path both for sure.
For me the diferenz is even bigger, my flat serve toss and swing are both decent but slice serve toss is already a problem. ( if my toss succeed decent, the swing seems to be a lesser problem...)

It's the same serve, turn your hand more for flat, less for slice. Let's not pretend this is rocket science.
