I can only speak on my experiences but I've had the least success with acrylics. It could be my technique, as I'm no great painter.
I've tried the 50/50 split enamel/thinner method and it is good to use to avoid clear coats, as it comes out shiny.
Personally, I love pre-thinned lacquers for how they spray for me, but you need to clear them.
In the end, your patience, practice, and personal preference will determine what's best for you. G'luck!
