Currently I use Fedora KDE spin because it fully suits me out of the box and while it’s packages are not bleeding edge, they are still relatively fresh. I had some stability problems with Void when I used it on my primary machine last time, so this was the only reason to switch to Fedora. I used Void for many years, and nowadays if I get some poor hardware (like old laptops or PC’s) I prefer to install Void. Can’t say if it any lighter than Fedora, but for me tinkering with Void is much more enjoyable
