I like the bowline because you don't have to guesstimate how long the rope around the tree needs to be. Easy to adjust, easy to untie. Make SURE to back it up with another knot.
Choice between webbing or cordage totally depends on what we have carried to the top of the crag. Some setups can be easier with one or the other.
