I got new wheels last year and there was a like $10 add-on to go tubeless straight from the factory with Schwalbe Pro Ones. Can't really compare it to the old wheels which were stock and had different tires but the new setup has been nothing but reliable.
I think going tubeless helped with vibration for longer rides -- I was previously looking for a more comfortable seat but am not so fussed by it anymore -- but that could just be the placebo effect or more riding. Definitely more peace of mind riding out to Elbow Falls before the sweepers hit the highway.
