Personally I think the Sunbrella (smoke grey) looks great and I've never had a negative comment, but lots of compliments. There is no sliding around on the seat and most important it breathes and stays cool on 100= degree days. Also warmer in the cold. The fabric was made for marine use so exposure to the elements does not damage it and it come in many colors so it's easy to get a more custom look. If I ever need another seat it will be an RDL with Sunbrella.
