Soyuz has only had 140 flights, and had some non lethal mission failures in recent decades. It’s a manned mission vehicle only though. Overall I don’t think you can really say one is more reliable than the other, they’re both very reliable. I’m just saying the suggestion that SpaceX approach is inherently less safe is very much contrary to the evidence.
Having said that I do think propulsive landing for crewed vehicles is pretty scary. F9 firsts stage landings have been pretty reliable for a while, and they now have several boosters with 10 or more flights, so we’ll see. It’s not like capsule landings are 100% safe either.
- bumby 4y ago>Soyuz has only had 140 flights There has been over 140 crewed launches. For context, you seem to be counting both test/demo, crewed, and uncrewed F9 launches. Again, I don't know the exact number off the top of my head, but there's probably ~10 crewed F9 launches, so it's an order magnitude difference using the same metric. It's gets better though, when comparing total launches.
