Every technology medium can have ping spikes. Cable, DSL, and WISP's in particular exhibit some level of jitter particularly if there's problem or interference. Fiber is going to be the most stable if there aren't underlying issues like weak light levels.
What I'm saying is if you can average 20ms and 1 out of 100 pings spikes higher, it will not make a huge difference in performance. The law of averages is what matters most. If jitter is low and packet loss near 0, it will perform well. The laser links between sats is absolutely crucial for them to be able to offer low latency especially satellites that are covering areas without ground stations. Without laser links, they wouldn't be able to offer service to airplanes or marine vessels over the ocean because the sats can't see land. With laser links, the data will pass between satellites to the nearest ground station, thus providing worldwide coverage. This network is the first and only promising LEO network that is actually providing public beta service. It sure helps that SpaceX has figured out reusable rockets and can launch 60 satellites per mission. This will only increase with their new starship as well where I believe they're targeting double that number per launch.
