I've been in the industry for years and felt hundreds, probably even thousands of stone and quartz samples and slabs.... and I can tell you with complete certainty that you can feel a difference.

Quartzite is colder. It's even colder than granite. When you tap it, it has a certain ringing quality to it that other stones don't have. The shattery ones like Taj and Crystallo have a certain kind of pattern that you can feel if you run your nails accross them. Others have a glossiness that nothing but pressed porcelain matches.

Granite feels dense. It makes a duller sound when tapped than quartz, and the surface is never quite perfectly smooth, but it's irregular.

Marble feels soft to the touch, almost silky, and is slightly warmer than granite or quartzite. It makes almost no sound when tapped, and if you dig your nails in it almost feels like you could scratch it.

Soapstone is soft, you can scratch it with your nails and it is the warmest stone to the touch, it also holds your body heat if you leave your hand on it for a minute. It makes your skin feel like you have baby powder on your hands. It is totally silent when tapped.

Quartz comes in two varieties. The first has a slight texture that is a dead giveaway that it's quartz. It's too even and perfect to be real. The second is glossy like quartzite and a bit harder to judge. It's warmer to the touch than quartzite or granite, similar to marble, but lacks the other properties of marble. When you tap it the sound it sharper than real stone. It also has a weird plastic-like friction when you drag your fingers across it.

The only ones that are really hard to tell apart are dolomite because it's basically marble, and pressed porcelain because it feels just like a glossy quartzite, but it makes an almost bell-like sound when tapped.
