If you perform just the comp bench in a low ROM highly efficient manner (which you should for the comp lift) then it’s not the greatest hypertrophy stimulus which is like super important for getting stronger. So yeh in that way Comp bench alone might not be the best approach or you’ll need to do quite a bit of volume/frequency for or.
I wouldn’t recommend getting completely away from the comp lift because IMO u still need to be handling relatively heavy weights in a close variation. Variations can present a new stimulus and target your weaknesses and increase time under tension in parts of the movement: Spoto bench for off the chest, close grip bench for overall ROM etc.
A little bit of heavy flat pressing variation at minimum then u can supplement with a load of accessory work if u find it works well for u.
Personally comp bench and some close variations like touch n go, Spoto press and long pause work well enough. I have a relatively close grip on my bench though so longer ROM. I do enjoy a lot of rep work on the dumbbells, incline press and overhead press though. If I leave the comp and close variations for a while there’s a reacclimatisation period which is a waste of time so I keep something in.
