The gold glove count is irrelevant. I know this because Derek Jeter has 3 of them.
It's almost impossible to compare them as fielders. Dawson is two different players. He was a top-flight CF wearing his knees out on a concrete outfield in Montreal, and then he was an averagish, in terms of range, RF after that concrete hobbled him. Evans was a stellar RF the whole time. Dawson was probably better before he switched, but he was worse after. If you look at BB-Ref, the numbers bear this out.
It isn't about only caring about sabermetrics. You look at stats to determine who was better, but if you don't know how to look at them, you won't get very far in your determination. The goal of sabermetricians has been to identify which stats actually contribute to runs scoring, the whole point of the offensive side of the game.
Of course Dawson had more H, 2B, HR, etc, etc. Over their careers they played in about the same amount of games, but because the Hawk wouldn't take a walk, he ended up with 1000 more ABs. By lauding him for his counting stat wins, and saying Evans "only" won OBP, you are punishing Evans for doing what should be the primary goal of every batter, to not make an out. There is no clock in baseball. The game is limited by each team getting 27 outs. Dawson made a boatload more outs than Evans, 700 more. This is why despite all those counting stat wins, Evans created 100 more runs over his career. Evans was the better offensive player.
