There are so many different factors that make a bike just good or awesome, the rear shock is only one element!
Especially at the 5k mark where you are paying enough to get a great bike but there are still compromises on frame vs suspension vs spec. Even a basic coil shock will mean a downgrade somewhere else.
Pick the bike with the best frame fit and geometry because that can’t be changed later.
After riding my Spec Stumpjumper EVO I finally feel like I have a bike that fits me right. That makes me happier then the 5% real world improvement that a higher end shock would give (I would love to put a coil on it though!)
