Quality of stone more important than anything. Cheap stone will wear infinitely more and cause issues.
How does one determine the quality of the stone? Price is a simple factor that can easily be deceptive by having a high price for a terrible product to seem as though it is a good product.
We have ivory travertine decking and had a large flagstone walkway installed from the driveway to the backyard. In the summer heat so far the travertine has never become so hot that it’s uncomfortable to walk on. However, the flagstone gets really hot and we have to wear flip flops. We are really glad we went with travertine.
What specific flagstone are you considering?
I would go with a sandstone or limestone.

For sandstone, the most durable is a quartzitic sandstone, which consists of interlocking quartz grains, cemented by silica.
You should inquire about the strength of the sandstone, which a good supplier should provide.
The stone’s data sheet should provide details about the compressive strength, the flexural strength, the porosity, the density, the hardness, the wet and dry Static Coefficient of Friction etc.
ASTM C616 classifies Quartz-Based Dimension Stone into three categories: Sandstone (Type I), Quartzitic Sandstone (Type II), and Quartzite (Type III). The stone is classified by the following physical properties: absorption by weight, density, compressive strength, modulus of rupture, and abrasion resistance.
Sandstone is the weakest. I think that regular sandstone is not a good choice in most cases. It tends to be too weak and does not hold up well.
Quartzitic sandstone is very strong and durable. It is composed of grains of Quartz bonded by Silica. I think that the best choice in most cases for decks is a quartzitic sandstone. It has a good texture, a good slip resistant surface, and very good weatherability.
Quartzite is stone that was originally sandstone but has been heated and pressurized in the earth into a harder and more durable stone than sandstone. During heating and pressurization, the grains of sand are melted together. This tends to give quartzite a slicker surface. In cases of water immersion, especially with a salt pool, I think that a true quartzite is usually a better choice.
Tennessee Crab Orchard Stone is usually a quartzitic sandstone. It is sometime referred to as a quartzite, but I don't think that it is a true quartzite. Many stone suppliers will be able to tell you the physical properties and composition of the stone, and to which classification the stone belongs. If there is any question, you might want to consult with a stonemason.
You want a denser stone that has less open pore space. You should get a stone with a density of at least 150 pounds per cubic foot and a water absorption by weight of not more than 3%. Water absorption can cause freeze/thaw damage, and creates more damage from salts and other chemicals.

Spalling of Limestone
We used leuders limestone for our pool coping. I live in Texas where it can get to 105 for months with no rain. 4 months after our pool completion, our limestone started spalling. At that time we had freezing temps, which causes spalling. At this time I had a chlorine puck pool. After...

Jerusalem limestone coping? Is it a bad idea?
So we had planned on putting Jerusalem limestone coping around the pool and spa veneer. But now I’m questioning my decision? Is this a bad choice? Thanks in advance
