AAAAAA UK Variant Vs International Variant

I am little confused that whether I should select the AAA UK Variant or the International, would someone please clear my confusion. If I select the AAA UK variant then will be eligible to work as an auditor in any country or for that I need to pass AAA International Variant. If we see now the SBR UK variant has also been discontinued so it means that there are no differences between the International Standards and UK Standards.
