6-string bass tuning vs guitar tuning

There are also EADGCF tuned 6-strings, but most bass players want that low B.

The bass is tuned in 4ths. The lower four strings on a guitar are also tuned in fourths, with G-B being a third, and then B-E being a 4th again. My understanding is this is purely for chord fingering convenience.

There are also baritone guitars.
