Throttle levers design in GA

[Flying Pinguin]

Good morning everybody,

First of all I would like greet all the forum since it is my first post here.

I have a question regarding the design of throttle levers on GA aircraft:

Most of the aircraft have a standard design, with a lever pivoting on a fixed point in the dashboard like PA28 or Cessna's etc..
Some others have the lever designed as a stick with a button at the end that must be pushed or pulled inside/outside the dashboard (i.e.: Cap 10, P64 Bravo, Zlin 142...).

I would like to ask what is difference and what is the use of each of them, if there is an advantage in the final purpose of the aircraft (aerobatics?).

Thanks for any answer!
