I use 4s because I get ~20% more playing time with 4s than with 0s, because 4s takes longer to eat thru gut probably due to 4s squoval shape.
So far after 4 hours on the court, it's hard for me to figure out which is better 0S or 4S. You are right, both play really well and you can't go wrong with either one. I guess tension maintenance will be the deciding factor between the two.
