Fact remains, they advise you to buy stuff because they want to sell stuff.
Neither product is specially good for that purpose. Both are just putting more distance between the paint and the substrate. You can use GAC or whatever other form of acrylic emulsion. Golden just happens to find a way to optimize their own production (produce just one product instead of 2 so they save money) that is why they change the recommendation.
Also I forgot to say in my answer. You said you sand down the panel before gessoing. If you do that, WASH IT and scrub it with a sponge and let it dry before you put ANY product on it.
Why? Because the tiny particles of the wood are the stuff that travels trough the acrylic, if you leave them there after sanding it there will be a lot more material to contaminate it. That is far more important then the specific material you happen to use.

One cannot simply be suddenly reasonable and reflexive in the internet, that breaks years of internet tradition as a medium of anger, arrogance, bigotry and self entitlement. Damm these internet newcomers being nice to to others!!!"
