The gap between the pads seems to be quite large, which means less floatation. On the McLaren tracks we have the rubber pads are about one inch apart when the tracks are straight on the ground, which also means less ground pressure and thus less wear and damage to the ground.
I like the continuous rubber OTTs, though. They offer the most floatation and traction and are safest for the ground. The only problem I see with them is that they are more expensive and once they break, you can't rebuild them.
