actually? i know this is an unpopular take but i've been enjoying clam blitz recently. (i hear i get a prize?)
rainmaker used to be my favorite - i find splat zones... still fun, don't get me wrong, but less interesting than the other modes, and i struggle with tower control as a dualie player (ending up on the tower in solo queue + needing to dodge roll to defend myself best = Not Great). i still really like rainmaker, but ever since i got comfortable playing CB at all i've been liking it more and more. i've never really thought about why, but maybe it's because in TC and RM, as an aggressive frontliner i try to take on the role of protecting whoever's actively pushing the tower/rainmaker rather than interacting with the objective myself (unless nobody's... pushing... the tower/rainmaker...), while in CB i get to play the objective directly while continuing to do my aggressive tetra thing. y'know?
