I was a die-hard enamel user until, like you, nsclcctl, I was forced to use some acrylics. Now I love 'em! The ease of clean-up alone is worth it, but I also love how smoothly they flow, no fly-away stringing, and the thin, even coats they lay down. I still use some enamels for airbrushing when there's a color matching problem with acrylics (some of the acrylic colors are a bit weak), but today's acrylics are really impressive. True, they often require two coats when one coat of enamel would've done the job, but, again, the clean-up, thinning, etc. is so easy that it's still easier than the clean-up of one coat of enamel.
Like TenchiMuto81, I find the enamel metallics are usually superior, so I usually choose which to use by the application.
