I used bases.chat, the AI program created by SABR member Ted Ingram, to get this data (2020 was excluded from the search).
The 1927 Yankees are by far the best (same thing happens with OPS differential). They had a wOBA of .392 and their pitchers allowed .312 for a differential of .081 (it is not .080 due to rounding issues).
