There is no best algo, every algo play within 3 dimensions
one is compression speed
second is ratio
third is decomp speed
Every algo can have 2 out 3 from the above virtues, so a masked process will always win over the classic process
no algo can have all the above, nanozip has best compression ratio but in terms of speed both comp and decomp it's useless
if there was a perfect algo then this masked thing would be useless :/
I hope i helped Amsal
