Which is better for a two way radio for skiing: Motorola or Midland?

If you are referring to VHF radios, not FRPs, I have used both for on-hill coaching, and have found the Midland to have better battery life. Range is determined more by terrain, Midland offers an extended antenna (about 28" long) which will increase your range dramatically. The only drawback to Midland, I find it hard to push the Mic on with gloves on.
