First, IMO, the best bedding is whatever dry organic material is readily and inexpensively available in your area. My favorite is pine straw -- free for the raking in my yard in season.
Straw should *in theory* be better bedding because it's a compost "brown" (carbon source), whereas hay and manure are both compost "greens" (nitrogen sources).
Theory aside, some people use hay quite successfully.
Chickens are tough, adaptable animals. Use what's convenient for you and if the bedding is loose rather than packed/matted, free of mold, and doesn't stink then it's working.
