This. In my experience the people actively disliking it have only ever used Jenkins 1 or somewhy only used freestyle jobs.

There are numerous ways to shoot yourself in the foot, though, and everything must be configured properly to get to feature parity with GHA (mail server, plugins, credentials, sso, https, port forwarding, webhooks, GitHub app, ...).

But once those are out of the way, its the most flexible and fastest CI system I have ever used.
