why is HS- a stronger BL base compared to HSO4

In a series of oxybases with the same central atom, the base with more O atoms is stronger.
In a series of oxybases with the same central atom, the base with less O atoms is stronger.
Since H2SO4 is one of the seven strong acids, HSO4- is a negligible base.

H2SO4 is a stronger acid than H2S, so HS- is the stronger conjugate base.
