Metal no doubt about it. Once you get into 8th grade or high school you just definitely get metal. The grip is better in the dirt, easier to run, less tripping/falling, etc. And you'll look pretty dumb playing hardball with moulded cleats. Definitely go with metal!
It depended on the field. If it is natural surface use metal. Is it a synthetic surface like astroturf or field turf they won't let you wear metal cleats on them you have to use molded cleats or turf shoes
