Depends on snow, last year I drove forward most of the time. Which is saying a lot for the snow we had. Didn't care for driving in reverse. I may of had to hit it a couple of times. If the load stopped the tractor, I would just spin around and clean it up with the loader, then restart. A couple big snows, I had the loader roughly up 6 inches to help clear some of the snow before it hit the rear blade. The approaches were easier to do in reverse for me. That was my first year so I'm still new to it.
This year I bought a front snowblower, its a new ballgame again. So far I like that. Nice and slow but I'm only touching it once and when I get the hang of it, it seems to cut my time in half from plowing. I still use the rear blade for clearing the approaches, mailbox and sneaking it into the garage since my BX is to tall.
