Anything labeled Dexron VI is going to be the same as it has to be certified to meet Dexron VI specs and approved by GM to be labeled such.
Dexron VI is expensive and I can never find it in gallon jugs locally so I use Valvoline MaxLife ATF. It's not certified by any manufacturers so it's much less expensive but it's fully synthetic and can be used in Dexron III/Dexron VI transmissions with or without flushing according the Valvoline. Walmart carries if in gallon jugs for under $18.
I have 292,000 miles on my 2007 Suburban and have used it since around 50,000 miles with no issues.
