Roof Shingle Manufacturers

Anyone have any experiences to share regarding roofing shingles? GAF seems to be the big boy on the block but I have a contractor who insists that ELK is better. Consumer reports rates the GAF Timberline Ultra higher than anything that ELK makes so I'm a little skeptical.
Thank you. SB
