Rolf, you might as well try it and get it over with. It's been recommended to you before. Once on it, you'll never want back off. It's that stable.
Print out both the beginner's guide and installation guides before you install, and follow them to the letter until you have the steps down in your head, from there you can modify them. Don't let the About scare you off. It will all be as familiar as rpm is to you once you start. I've run it for years off and on, and had the same problem when I went from it to rpm. I found the rpm distros not anywhere near as stable, and had a time figuring them out. But as anything else, the more we do, the more we learn. You could certainly do a LOT worse than Arch, and have with
any other distro nowhere near the bleeding edge rolling distro, nor be able to do it with rock-solid stability like Arch does.
You don't do "slices" or anything else mechanical like BSD does (although I wish it did, being a huge BSD fan), you have your / (root), /swap, /boot, and /home, just like any other normal distro. You will see how it is BSD-like once you're into it. It's more a mindset kind of thing, and the way it "does", or "acts", for lack of better words. I can't really verbalize or describe it well. Just believe me, and trust me this once, in saying it is indeed something that's right up your alley.
Oh, meant to mention also, that Arch has one of the most gorgeous implementations of KDE of all. It is the only distro that I will even load KDE on. If you like being the first to try out new KDE versions, then Arch is definitely the way to go. I know you love KDE; do it the beautiful way.
