We are currently picking out our pavers for our pool patio and I see pool coping done in two different ways when looking at designs, One has the bullnose coping butting up to each other, the other one has a grout line in between the coping pavers. Is this done for any specific reason or just for looks? any help would be greatly apppreacitated.

Grout allows for less precise cuts whereas without needs much more precision. Grouted should be a good deal less expensive
I've got a pool coping question to add..
Why do I notice on poured in place coping there a piece of plastic between the pool tiles and the coping? I don't notice it on pavers or did they chose to leave it out? Is that there to seal the coping to the tiles?

It allows the coping/decking to move independently from the pool walls. Without it, the waterline tiles could crack/break from any slight settling/movement of the decking. Sometimes a small gap filled with silicone or another flexible sealant is used rather than the plastic.
My waterline tiles were installed prior to my cantilevered decking being poured, and they back buttered the tiles rather than applying the thinset to the pool walls. This created scallop shaped gaps between the tile and wall at the very top. When they poured the decking afterward, the concrete seeped into these gaps, which were just behind the plastic strip. Many years later the decking settled slightly on one side, and heaved slightly on the other from some tree roots, and some of the tiles broke because they were in direct contact with the decking. I'm in the process of grinding the protruding scalloped shaped pieces of decking off so that my new waterline tiles don't experience the same fate.
Great info, I figured it was for expansion but wasn't 100% sure. Wouldn't the plastic hold up better then silicone over the life of the pool? I could see having to replace the silicone every few years out here in Nevada.
