The electronic suspension, cruise, heated grips, and handles did it for me to make me want the higher spec bike.
I've only owned the ES but I really dig adjusting that suspension. I was on a trip a couple of weeks ago where the pavement became harsh with expansion lines. I dialed it back to soft, softened in more, and the ride was so much better for the next 64 miles.
And cruise control, don't get me started. It is the best thing to happen to a motorcycle. We all end up on a boring stretch of highway sooner or later and the cruise gives you so much more flexibility with fatigue management. And yes, it is a lot better than a cramp buster or throttle lock.
If you can't find an ES local don't forget about Uship. Very good rates there and my buddy has used it three times to move bikes with no troubles. People bid on your job and it's probably the cheapest way to ship a bike. Well worth it.
