I think they're both gorgeous.
You probably should check with your local council - get it in writing (via email will do) that a dog like Kobi would be ok to register there as a Staffy x. Send them the link.
Queensland seems to be having the biggest problems with wanting to kill any unidentified breed dog that might be a pitbull. This can include Staffordshire Bull Terriers - frequently confused by ignorant people, like news reporters, with American Staffordshire Terriers and/or Pitbulls - in Queensland. Maybe they're a bit slow up there.
I have a personal preference for girl dogs cos mostly they don't cock their legs on anything. And there's more belly to rub.
