I have an 09 HCR. I chose one over the standard for a few reasons. I liked the Boss Seat, which doesn't come on the 2010 model but the stock one is probably just as good anyway.
Other than the seat, I like the titanium springs on the front shocks as well as the clutch. I like the responsiveness of springs on my shocks and find them more reliable than air only. A titanium clutch spring will give a more consistent result throughout the day, no matter how hot it gets.
Whether you feel those items are worth the money, only you can answer. As I get older, I have less and less time to tinker with things so getting a stock setup with what I like is just the way I choose to go.
