Well there are of course big diferances. The amazon rocket is very slow. Only 3,5 mach, elon s has 10 mach speed. Amazon s rocket is also much more lighterhas only one engine Elon s has six. This makes elon s task a magnitude more troublesome.
it isn't a speed contest. Space X is pursuing ferrying of cargo and astronauts to the ISS. Both want to be reusable.Bozos wants space tourists to get relatively quick "rides" to space and back. two different goals/markets. Elon has a rocket that does a somersault then comes back..he has contractual obligations to stick a landing on a floating barge before he can get a lease for a NASA approved perm launch site in Florida. Bozos has a huge accomplishment to his credit. Elon has aimed quite a bit higher.
