I just gave you first hand experience and I'm not backed/funded/paid/sponsored by any company/brand/manufacturer/agenda like 99.9% of YouTube, it is unfortunately the sad truth in 2019.
The gamers nexus review is honestly complete rubbish I assume his PC is in an oven? I have no clue how he managed to get his temps that high.
I don't doubt that aibs are cooler but it operates well below it's thermal cap either way so you gain nothing other than hwinfo showing you a different number.
Personally I'd definitely avoid Pulse since my Vega 56 Pulse had that obnoxious high pitched sound which is actually super annoying.
But hey do whatever you want it's your money haha
