I am currently using the new small style but I would prefer the old one with larger buttons myself. I think for overall functionality & safety its a better choice. While you may have more options available with fewer button taps on the small style; you have to focus more to see what the heck your selecting. So what if the map gets covered for a few seconds, I could probably get around faster with the larger buttons. Like most others have said, the larger ones would be a better choice IMO.
