When installed as recommended by Certainteed(details on their site) they give a 110mph wind warranty on Landmark shingles and 130mph on Solaris and others. Homeowner's insurance also covers wind damage.
Metal roofs almost always are more thermally reflective, but many don't like the look/cost/rain noise. I'm required by my HOA to use asphalt shingles.
