What has driven my choice in a c/p is pure protection. I got my heart rhythm disrupted by a foul ball in 10 year old game, while wearing a cheap, ribbed protector. I switched to hard shells right after that, and that was a dozen years ago.
I've recently added the System 7 to the front of my bag, and there it will stay. I've never heard anything close to any protection issues with this rig. No gaps, no cracking plastic plates, etc. It's the only one, aside from the Platinum, that has one solid plate from the chest to over the shoulder. That's the best collarbone protection there is.
Choose what you wish, but just do your homework. We all go on the field accepting some sort of risk. I choose to use really good protection for my heart and noggin.
