Tubeless is trendy, so go tubeless to protect yourself from people telling you to go tubeless
FWIW, I didn't notice a difference in ride last year when I mounted a set of WTB Horizon tires (47 mm) tubeless for a few days. Both bikes -- tubeless and tubed -- felt the same when I rode them. However, tubeless with sealant would provide peace of mind against flatting from a piece of say, glass. That's where I see the advantage.
