I rode my 2012 Spyder RS with the OEM seat for some 3K miles before I upgraded to the BRP Comfort seat. Honestly, my butt couldn't really tell the difference.
After another 5K miles my butt finally adapted to riding as opposed to sitting in a car or truck seat, but I can't really say the Comfort seat was any more or less comfortable than the plain OEM seat was. The Comfort seat mainly just looks better IMHO, it's a styling upgrade more so than a comfort level upgrade.
Butt, that's just my opinion. If you get it at a good price it's a nice styling upgrade, butt your butt will probably just need a couple thousand more miles of riding time before it stops complaining.
ps. Your butt won't hate the upgraded seat it certainly isn't worse than the OEM seat, but it won't be celebrating it either.
