Ruth/Bonds tier. Both orders are fine. The best offensive seasons in history are basically an even split between '20-23 Ruth and '01-04 Bonds.
Then Williams has to be near or at the top of T2. That's the 3rd best peak and the 2nd most consistently elite after Ruth.
But there are two elephants in the room. One is Josh Gibson, which I know won't surprise you. What might is that he's now the career Major League leader in wRC+. Williams is 3rd at 187. Ruth is way up at 194. And then there's Gibson at a completely absurd 202. He's also the career leader in wOBA. But the sample size is only about a quarter of Williams and Ruth. Then the one that never gets mentioned in these things is Oscar Charleston. He's 4th in wRC+ at 181, well clear of everyone not mentioned yet. I don't think he was a Tier 1 contender, but if you're a peak voter, he should probably be on T2 or at least T3.
