What is the better version ? SDL or QT ?

[[Unknown]]

Qt has some native menus, but only supports OpenGL. It also has better font support (most important for certain non-Latin languages.)

SDL is better maintained and supports Vulkan. All options are still available in settings, just not via native menus.

Both use SDL for audio and controls, so those shouldn't be any different.

Performance should be roughly the same but may be better on SDL due to being able to use Vulkan.
