29er used to get fairly regular punctures, when i went to stans rims and tubeless without even using tubeless specific tyres I have only had one puncture that did not seal properly, and that was due to the sealant having nearly dried up (even that was only a slow puncture and I did not need to put a tube in to get home) other huge benefit was lower pressures and more grip
road tubeless is slightly less successful but still better than puncture resistant tyres and their shit handling
Tubless mtb was totally worth it for me.
