It's definitely more efficient. I've had it mapped that way for years, and after a short time it basically became a single keystroke.
The efficiency doesn't come from the fact that it's not as far to reach. The efficiency comes from the fact that you don't have to find home row with your left hand again and can continue your command sequence immediately.
