it does cost more, and it's just my personal choice and recommendation.
If one is hard on the brakes, and/or just wants the extra piece of mind.
In my write-up I do say that no matter which you choose, just be sure you flush and fill regularly.
It's like conventional oil Vs synthetic oil, which brand, viscosity, etc... age old argument, and endless threads have later it still goes on and on.
DOT 4 is fine, just like years ago DOT 3 was fine, but time, and braking technologies change, and DOT 4 was needed. So who knows when DOT 6 coming.
DOT standards change as the industry changes.
