Same as fibre? No. Same as broadband generically? Pretty much. I've used it and it pretty much lets most people do what they consider normal internet stuff (including streaming video, video calls, etc.) I'm not a gamer so can't speak to stringent latency demands.

Note that Starlink is LEO satellites so different from geosynchronous satellites in terms of latency.

Latency is surprisingly good, usually under 20 milliseconds. Not the same as a wired connection obviously, but plenty good enough for almost every application.
