for monofilament filament, the round diameter is about 214 micron for multi filament yarn depends to cross section of fibers and the rate of twisting
"2400 Denier Polyester and 900 DenierMicro-Polyester fabric"
600 x 300 denier is slightly less quality than 600 x 600. The weave is also different
Denier polyester is fabric and the higher the number, the thicker and stronger it is. 210 would be thin like silk.
The strength of polyester fabric is typically measured by its denier (d), which refers to the thickness of the fibers. A 240d (denier) polyester fabric is generally stronger than a 240g (grams) fabric, as denier indicates a heavier and thicker fiber that can withstand more stress and wear. Therefore, 240d polyester is likely to be more durable and resilient compared to 240g polyester.
Nylon is more durable than polyester. Also, when comparing 840 denier to 600 denier of the same fabric, the 840 denier is thicker, rougher, more coarse and stronger than the 600 denier. So, on both counts, the 840 denier nylon is more durable. If you look at the following link, the tan soft dog crate is made of 600 denier polyester and the colorful soft dog crates are made of nylon.

no denier mean the density and fibre of the fabric
I don't know about the 600 denier polyester fabric but a mouse in my house chewed through some of the man-made material of the sandals in my closet! They were a thick metallic fabric.
