If you want to know which is better, make a batch of both. The only thing with baking is unless EVERYTHING is exactly the same(humidity, etc), it's really hard to make a recipe exactly the same every day. If you measure flour with a measuring cup and not by weight, you will get different amounts depending on how you measure. Flour holds different amounts of water depending on the humidity in the air. I make bread and you have to adjust the flour-I never measure at the end but I know the recipes I use takes different amounts of flour every time. Depending on the brand of butter, there may be more water, less fat which will affect the final product.
I have participated in trying to find the best chocolate cake recipe on another side. Everyone has different ideas of what a certain bake good should taste like and they are never the same as yours LOL. I can bake the same cake as you but my oven may be hotter and my cake overcooks and I find it dry while you cook yours perfectly and it's nice and moist.
So try both recipes but I would stick with the one I get consistent results with and "most" people enjoy eating. I really doubt there is a "best" recipe out there for bake goods-just really good ones.
