My parents are on Sky Muster in Australia and it works fine for them, we call them a couple times a month and the latency isn't amazing but I've had worse calls with people on DSL.
My subjective opinion was that the starlink was better than DSL and even better than some cable internet services I’ve subscribed to in recent years. The downside of the starlink was that it would sometimes drop out for 8 seconds, but I’ve had cable and DSL that would fail for half an hour. Apparently the dropouts have become much less common in the last year.
