The Giant Gavia tubeless tyres that came on my Defy were absolutely fine. No issues at all. So if they are one of the worst tubeless setups, then all is good! I've just replaced the original Giant tyres with Pirelli Velos, which were a bit of a pain to seat first time (required a boost track pump), but are otherwise fine. I've been running tubeless mtb tyres for 15+ years without any issues, so for me tubeless road tyres were a natural choice. The main reason I prefer tubeless is for extra puncture protection. I still carry a spare tube as a last resort, but never had to fit one yet.
