Maintenance perspective on suspensions
There is no disputing that hardtails require less long term maintenance. All of those pivots and linkages on the FS will need periodic servicing, and the rear shock will need new seals every season or two. Frame articulation causes cables to rub on the frame, and the chain has to work harder to keep up with everything. If you enjoy simplicity and want to keep your maintenance costs low, a hardtail is a good choice or a rigid for that matter.
