i would go for fat b but you have no guns so disintegrator

I would go Fat bullets personally, The bosses aren't tooooo bad by that floor and fat bullets is a permanent damage buff for everything throughout the rest of the run and will help on all rooms of all floors, grab a boss killer next floor (I am assuming this is a rainbow run, if this is not and you are in a shop grab the disintegrator because chances are you wont see another S tier)

fat bullets it is then. I'll be fine on this floor. Yes it is a rainbow run.

the Disintegrator for me is not a boss fight item because of it loooooooooooooooooooooong charge time and you have to dooooooooogle roll more often when you fighting a boss
