I prefer fWAR, I think FG is easier to navigate than BR, ha. The answer is probably a blend of the two to find true value. The super easy way to explain why I like fWAR more is how fWAR values the underlying things guys do vs bWAR going off of more what guys actually did on surface numbers. Is that still true for hitting and defense stats? I'm pretty sure they are very similar, UZR vs DRS for defense, and both use wOBA as the base for their offensive WAR. I think B-R actually normalizes for league more than FG does now. With pitching you still have the RA vs FIP situation, but for hitters idk that FG is really more about valuing the underlying things guys do than B-R these days. You might be right on hitters, but pitchers are definitely different and I prefer the FG way of measuring that with FIP.
