Neither.
But Pullovers hit the inner pecs if done right.
...
So you have inner pecs
Serious note;
dips = compound excersise;
it hits triceps, chest and shoulders.
Pullovers,
shoulderwrecker,
but the funny thing is,
people who claim that they can't do behind the neck-press, love this excersise.
Pullover btw does jackshit,
it hits the abs, back, but it leaves the chest.
