It seems like prettier is more legible in general. For something like box-shadow, biome splits based on line-length whereas prettier is splitting on the comma.

e.g.

.prettier {
  box-shadow:
    10px 10px 10px 10px rgb(10 18 30 / 12%),
    10px 10px 10px 10px rgb(10 18 30 / 16%);
}

.biome {
  box-shadow: 10px 10px 10px 10px rgb(10 18 30 / 12%), 10px 10px 10px 10px
    rgb(10 18 30 / 16%);
}

Even in the case where it all fits on one line, I find it easier to read the multiline version like it works in prettier:

.prettier {
  box-shadow:
    0 2px 2px 0 rgb(10 18 30 / 12%),
    0 0 2px 0 rgb(10 18 30 / 16%);
}

.biome {
  box-shadow: 0 2px 2px 0 rgb(10 18 30 / 12%), 0 0 2px 0 rgb(10 18 30 / 16%);
}

I could try to solve this.
