They all look OK to me. But primer deformation's not all that great in judging peak pressure from. They're not all made to the same metalurgy properties and dimensions so one will deform a lot with a given load and the other not much at all. And a tight bore rifle will cause more primer deformation with a given load than an oversize one.
