JMHO, Nothing is better then the RZ seat - NOTHING. All other seats are static which means the surface area doesn't change at all. Pressure points stay the same. RZ seat can be infinitely changed so there is no set pressure point. I've had 2 RZ seats, one for the older bikes and the new model I have now that I switch from bike to bike.
Even without the air bladders, I feel the design of the RZ seat a lot more comfortable than the stock seat because it is so much wider which means more support area.
Unless you can exchange the seat if you don't like it after a couple months (which is about how long it takes to see if you really like it), buying an aftermarket seat can be very expensive if you have to go through multiple seats to find the correct one.
If you don't plan on long distance trips, buying an aftermarket seat is throwing away money - IMO.
Before buying any seat, at least take it for a test ride.
Other than your mufflers, the seat is the biggest/most important decision you will make.
Good luck.
Forgot to mention, the RZ seat will sit you a little bit closer to the front. You can still raise/lower the height.
