The best specialty paint available on the market is called COOL LIFE produced by the LIFE PAINT company in Santa Fe Springs, CA. Good luck finding another product out there that warrants against cracking, flaking, and chipping. Because of the scrupulous application process, make sure you are working with an authorized dealer, like Reliant Home Solutions 
I have had chalk board paint for the kids for years and it has held up very well. I would not recommend suede for durability. It would depend on what you are trying to achieve.
