DBF did a bunch of research on these as he wanted to order some for an event he will be doing. Here's what he said "You can't go wrong with Marathons. A heavier tire has a thicker tread which will be more puncture resistant. But I'd definitely recommend getting the ones with the reflective stripe on the sidewall."
Hope that helps.
