I don't want to divert the thread but whilst I'm not surprised by a preference for acrylics I am surprised that people find them easier to use.For spraying in particular surely enamel paints are easier. Acrylics can be tricky,drying at the nozzle etc,and take a bit more effort to master. Also thinning acrylic paint is far more particular.
With enamels you can chuck in turps,white spirit or even cellulose thinners fairly inexactly and still get a good result. You can't do that with most acrylics. For newcomers to spraying them I always advise using the same brand thinners. Later they might try their own thinning,water,ipa etc along with flow aids and retarders. None of this is required with enamel paints!
Just my opinion.
