I already read the whole thread, you got many responses to your question; I suggest you to read it again yourself.

I imagine that would depend on what you mean by "preferrable", and to whom it applies.

I don’t think there is a way of knowing for the ideal first move in chess. The game is still an unsolved equation. As long as it remains a problem, and we could not resolve with absolute certainty of its ending, it will remain a mystery. For how can we talk of an ideal beginning when we don't even know anything sure about the ending? However, we could make reasonable judgments based on the precepts laid to us by the 'experts'. e4, d4 and c4 are among the most sensible moves. I would like put my bet on e4. It is dynamic and very principled. I’m sure Bobby Fischer will agree with me!

Speaking from my own personal experience over the years on ICCF, 'perfect' chess is most definitely a draw, and there are probably untold millions upon millions of different ways to play a perfect game.

Consider 1.e4:

I've demonstrated in the past that even against ultra-powerful computers one can force a draw as black with the Petroff, a database, and a desktop computer. Thus, if black wants to draw, white cannot avoid it.
