It might depends. People made bench press arbitrary, doesn’t mean it will work for everyone.
The questions you have to ask yourself when doing swiss bar low incline press is « Do I feel like my targeted muscle is responding well to this exercise ? » « Do I feel fatigue in the targeted muscle after my sets ? »
If you get a massive pump doing it then it’s great for sure. If you feel like it kinda does nothing, maybe try different bench angles or hand positioning.
Hope it helps mate.
