Costs more, probably eats battery faster. I'm happy with mine. My main commuting bike has a steady-on dynamo-powered tail light plus the Cygolite. I also use a Spoke Lit in the rear wheel, which I'm told does a good job at catching eyes. Bigger (or really, brighter) may be better, but there is a point of diminishing returns. I suspect I'm at that point already.
