Just wondering what peoples thoughts on this are...

I never really did weighted dips, but did them fairly fresh today, and decided that i prefer them to Decline bench. They targeted more areas of my chest than i have generally felt, and i felt alot safer doing them. (i have no spotter.)
Does anyone else swap the dips for the decline?
Anyone think one is better than the other..?
Anyone think that they are completely different excercises?
