I won't try to say which armor is the best choice for anyone. But there are many good kits out there I have an Anovos stunt kit and a WTF Crimson kit both are decent enough for me and I've had no issues with either so far. When I built my Anovos kit I literally only had access to sandpaper, utility knife, dremel and some kitchen shears. So you can manage with minimal tools. Don't think or feel you need a lot of tools basic tools like a hammer, screwdriver, utility knife, x-acto knife and sandpaper and a snap setting tool is all you really need everything else is just to make it easier.
Good luck with whatever armor you choose and I look forward to your build.
