That very much depends on your setup. map can be the faster, slower or equal variant. There's too many constraints that play a role - you can't just say "this is faster" based on a minimal benchmark because the characteristics of each looping approach lend themselves to different data structure and control flow designs. If you take a forish approach, using map instead will be awkard - but the same is true in the reverse case.
