There are no pros or cons beyond the question, “Is it enjoyable or not?”.
Robert Heinlein’s ideology was all over the map, but he was a damn good read.
A few of the stories are an attempt to be as conservative ideological and parodies as many liberal message fiction pieces are, and fall flat.
I’d say a majority of the stories are good, and the Christian science fiction stories in it are EXCELLENT, notably one with a Muslim coming to Christ while challenging jihadis and another involving alternate timelines.
