Loco is on the money – Tubeless you can run @ lower pressures but here is as I see it (talking generally).
Std rims with kit + Std tyres = harder to inflate and may burp at lower pressures and side walls may not be strong enough to prevent tears.
Tubeless ready rims and tyres = easier to inflate, sl thicker side walls and valve and tape needed but unlikely to burp or rip.
Tubeless rims + tubeless tyres – much easier to get up, burp rarely, bit heavier d.t. the thicker side walls but don’t need sealing.
All benefit from milk inside the tyre :)
