Need advice

More workload = more hypertrophy

A bigger muscle is a stronger muscle. It’s pretty simple, lift more weight

Likely #1. However, if you used poor technique for #1, used quick negatives and didn’t hold tension, and never got close to failure and conversely did controlled reps with #2, utilizing long negatives to increase total tension, and got to failure or close to it, then the chest would likely grow more from #2.

everyone is going to give you a bunch of BS,

but its simple for chest

get strong af on first on barbell bench/incine then DB Bench, Incline DB bench, weighted dips and weighted ring pushups

if you can get your waist to 31-32" at the naval and hit the following standards...you will have the chest you want

bench-1.75x BW
incline- 1.5x bw
dips- 1x BW for 5-6
incline weighted ring pushups- 80lbs x 10
db bench- 125s for 8
db incline bench- 100s for 8

Intensity matters whether you are doing 3x5 or 3x15.

Food is how you put on size. Real Food. Eat plenty of Ground Beef, Steaks, Eggs, Bacon, maybe a little chicken or fish thrown in. You can train until you pass out but if you aren't eating right you will not grow or if you have insane genetics you might grow some but you will hit a plateau you will not be able to break through without food. Real Whole Foods are the most anabolic thing you can put in your body besides actual anabolics themselves.
