EMG studies do show that the decline benchpress does indeed hit the most pec fibers with the least amount of front delt recruitment but this is because for most people the majority of there chest fibers is the lower to mid pecs at the sternal head.
For the average man, there's less muscle fibers at the clavicular head of the pecs unless your a genetic freak like Franco Columbo and others.
Check out the Barnett study on all bench press angles and grip placements. Here's a link right here.

Check out how they studied the reverse grip benchpress and it turned out that the reverse grip benchpress hit more clavicular head of the pecs aka upper pecs more so then even the incline benchpress.
In the study it also showed that there was no big difference in upper chest stimulation between the flat benchpress and the incline benchpress.
This shit seems to always change lol! Before it was decline was the go to press for chest, now we're back to incline lol!! Maybe I gave up on inclines too soon/wasn't executing them right
Hey Pitbulltank. Heres a side chest pose shot taken today. Keep in mind I'm flat and depleted from extreme dieting. Dropped almost 30 pounds in 9 months to get shredded and still going.
The second pic is of me standing relaxed sideways so you can see the under development of my upper chest that I'm talking about making it look like I have breast.
imo decline makes your chest bigger, while incline makes it look better, if that makes any sense lol... i use to do purely declines and weighted dips, chest was big but when i switched back to doing incline work i def noticed a much better look and fullness in the upper chest esp seeing it from the side view...
also to the OP- hit a side chest pose and show off the upper chest... i don't know too many people who aren't freak big that look like they have a huge boulder upper chest popping off them from the side just relaxing...
