HSO3F is a super acid which is 100% greater than sulfuric acid. It has Ho which has pKa -15.
Flluorosulphuric acid is a superacids which is 100% greater than sulfuric acid.
HSO3F and Lewis acid antimony pentafluoride gives Magic acid which is far stronger protonating agent.
These all come under category of superacids which are 100% stronger than sulfuric acid.
HSO3F acidic strength is greater than any given species.
HCO3- pKa is 10.25
H3O+ pKa is -1.74
HSO4- pKa is. 1.92
HSO3F pKa is. -15
Less pKa more acidic strength
So,
HSO3F > H3O+ > HSO4- > HCO3-
