I wouldn't be too concerned about the width. On a 50x60 area, you will do 23 long passes with a 32" and 26 passes with a 28", so it's not a significant difference to me. My main concern would be how far it can throw the snow, which requires power. If it cannot throw it 25 feet away then you will have to move the same snow twice instead of just once. And if you have to send it diagonally to your own property instead of sideways to the neighbor's parking then it needs to throw even further (also higher because snow banks get taller over the course of winter). Your main regret would be to have bought something under-powered for your needs.
