>Does anyone think GHA is better than Jenkins?

A 1000% yes, because it means the default experice most devs have of CI is using ephemeral runners which is a massive win for security and build rot.

Every company I've worked at with stateful runners was a security incident begging to happen, not to mention builds that would do different things depending on what runner host you got placed on (devs manually installing different versions of things on hosts, etc)

Does anyone use GHA - full stop? Their stuff seems "me too" in most cases, they are definitely a follower, like microsoft Bing search ... google AI ...
