Using FSRS, I think that the recommended settings are maybe reduced and simplified.
The big difference is that FSRS doesn’t use the “Ease Factor”. Instead, it uses “Stability”, “Difficulty” and “Retrievability”. According to FSRS4 Github issues, there is a function to alleviate Ease Hell, so the previous solution for Ease Hell is not necessary. FSRS can also be alleviated by changing the retention rate value.
And FSRS4Anki Helper integrates the same functionality as the standard add-ons. So, if FSRS and FSRS4AnkiHelper are used, there is no need to use these Add-ons for adjusting Ease and schedule.
