Body armor kits

I've recently become interested in body armor kits, and I'm trying to figure out what to choose. I'm considering buying a ready-made kit to get a well-balanced solution right away without the hassle of choosing components. But I'm not sure if there's any real benefit to this, or if it's better to assemble the system myself. Ready-made kits are usually designed for compatibility and weight, but custom assembly allows you to select only the necessary elements and avoid unnecessary ones. I wonder which is more practical: a factory kit or a carefully selected combination of components?

I think it's more convenient - there's less risk of making a mistake with compatibility.

When I was looking for all-in-one kits, I found these kits on rtstactical. On the website, you can choose an option where everything is included in the body armor kits, eliminating the need to search for individual plates. My colleague bought one first. He needed it for work, and he said it was convenient to have everything in one kit. Then I bought one myself, and I haven't regretted it. The website shows the contents of each kit, which saves time. If you're new to this, these kits help you avoid mistakes. I was just researching, but the information there is useful.
