I think flat black looks too "unfinished" to me. Almost like you wanted to get a paint job, but could only afford the primer.
Now, satin black on the other hand. That's a beauty to behold. I've actually considered repainting my Subaru in a Pearl White/Satin Black two-tone.
Here's my friend's 240SX done up in Satin Black. It's hard to believe he did this himself in his garage.
Or even better, this Lotus I found on the internet.
