At our level of play, your only important task in the opening is to reach a middle-game position in which you feel comfortable and confident. Whatever sequence of opening moves gets you there is the "best" opening for you.
Actually, at any level. Don't you think so?
Pretty much, yeah.
Grandmasters might have other motives than "reaching a comfortable position"... but for players like us, this maxim will do.
My most recent foray with the London got me a nice playable middle game where I had trouble finding a plan. In the ensuing play, I made a poor decision at the point where I had an advantage and my game fell apart.
