The 1st thing that popped into my head was are you wanting to be more of a powerlifter or bodybuilder. If your wanting more of that BB look, def switch it up. Maybe your upper chest is a little weaker than you want thus hit the incline, decline, then swallow your pride for a little bench...lol for ex.
If your wanting to be more of a powerlifter, car thrower, stick with that bench. Many guys have said it but barbell is the way to go for power hands downs.
Personally, I usually only touch dumbbells for flyes but that's my thing.
