I hate ZR with a deep passion. It's incredibly volatile and based on many factors that can't be conditioned for equally across all boards.
I agree that there is no great way to judge fielding a 100%, but one metric I do like is fielding win shares.

They judge fielding differently for each position since different skills are needed to play each position. For example, when considering how good defensively a catcher is caught stealing is weighed more heavily than passed balls to give a true measure of fielding talent for the player.

It also equalizes opportunities for the fielders like for example, if a team uses left-handed pitchers more often and as a result certain fielders don't get as many chances, that is accounted for.

It's not perfect, but it's pretty good.
