Same here, LSE, LSC, and Cloudfare Enterprise and presently not aware of anyone outperforming us at present.
QUIC is a joke (like a shitty game with micro transactions), Bunny is decent (would actually use this more if it actually meant anything to our clients, however it does not, and CFE does what we need it to, performance and onboarding clients).
Will also add we're not ignorant to nginx, we spent most of our lives using it. But after switching to LSE, LSC, I can't imagine going going back to Nginx at this point.
