Nope, never said it would be terrible, just that it wasn't as capable as a solenoid-based or other more advanced system.
You don't need ES on a trackbike; it's just not a complex enough environment to need the adaptability. The road is where the value is, and if you're looking at a Ducati then yes, the S is the way to go. For tracking you could buy a base and some aftermarket bits and probably end up better for pure pace, but it wouldn't be nearly as flexible a bike.
The S suspension and that on the R1M can be looked at as equal, save for how the two companies tune their installation (and that would be the same for non-ES bikes with same model Ohlins at both ends). And that last bit is simply an unknown variable at this time. Time will tell of course, but I expect the BMW will likely have the best suspension of the lot for all-around use.
What turns out to be the best all-around machine is a much more complex question and one that can have multiple answers.
