Which opening is best For both white and Black

please tell your answer

the Sicilian defense

Kings Indian defence/ attack

Kings indian but that is my opinion

The usual answer is the Ruy lopez,
but I do not know if.
The Spanish game, Ruy lopez was a spanish priest,
an old master like Lucena.
I need to check a little chess history to remember it,
I think Lucena was Italian, and there is an endgame study for him, rook endgame perhaps.

if white do 1.f3 ..2. g4 (best suggested opening!!)
if your black do 1..f6 2.g5 (superb!!!)

yeah i know this is a joke lmao

it think for white side colle

and

from black side sicillian defence

is best from my side
