Default Reedy 540-SL vs 540-SL4 motors

These are the sensorless motors that come in the rtr kits. The old 540r motors and the 540-SL motors that replaced them were 2 pole. The new 540-SL4 motors that came out over a year ago are now 4 pole. Has anyone driven each and done a performance comparison between them? Are the new ones faster/slower, smoother, hotter/colder, longer/shorter runtimes? The street stock oval class here puts strong emphasis on running 3300kv rated sensorless motors and the Reedys are popular and plentiful. I'm looking for the differences between them.
