Owned a Frosty and it was very forgiving. Cleaning it definitely brought out the glow, but not cleaning it was fine for a while.
I currently have an Ebony. Every scratch, every swirl, every blemish shows up. It's a nightmare to keep clean and requires specialist products to detail it. It can take 4-5 hours to prepare it for a show... and then once you get there it's covered in pollen and dust. Removing that rubbish once you get to the show means using a waterless wash. And even then you need to give it a wipe over now and then, unless you're at an indoor show.
And of course if you do go to a show, you're going to get scratches that show up in a way that they wouldn't on a Frosty. Bags, zippers, buckles, children.
But you know what? I would own another Ebony in a heartbeat.
