In cash games, getting in when you are 53% to win is great if you have good BRM. In tournaments, whether you take the small edge is entirely about whether you think you get better chances later in the game. If you think you are outplaying the other players, by all means give up this battle (if the pot odds
don't demand a call) and take the greater edge later.
If you have a large stack or feel you could eliminate a better opponent (Gold vs. Cunningham for example) you might want to take a small edge an occasionally even a slight disadvantage if you feel that the odds offered are better than that you get from playing your opponents another way.
All ins preflop do not turn a game of skill into a game of chance. They simply make the skill come before the flop, and the chance come later.
