Payload, I use Linux on a couple of RPis (Lubuntu or Xubuntu) I have and also a few older laptops. XFCE and LXDE are lightweight windows managers that add some speed you'll miss with KDE. I've found on my underpowered machines, they can work quite nicely with Linux.
But life with Linux is kind of the wild west. You may get into some situations where the only way out is confusing and arcane. But there is also a large base of users who will gladly help you out, just as with Mac and Windows. Personally, I'd say ignore those who tell you how they hate it because of a 20 year old experience (based on that, I don't like my 4 Macs or my older PCs with Windows either.) Ignore those who tell you it will slice your bread and make dinner and all the while it is also saving humanity. Pay attention to those in the middle.
I would also STRONGLY recommend doing your testing in Virtualbox VMs until you find what you like, IF you find what you like. You can find a bunch of pre-built and safe VMs from http://www.osboxes.org that you can test out without having to install them. Just download and play. Initially, rather than deciding between distros, check out the different desktops first. XFCE, KDE, Gnome, LXDE, etc. and then decide about the underlying distro. Believe it or not, there ARE significant differences between distros, and between windows managers.
I used to hate Linux, but now I love it. It's fun to tinker with and cheap to use- especially if you recycle your hardware. I tend to prefer the Debian based distros, but the Red Hat ones are just as good if that is what you are used to. The great thing about it is you can play all you want and invest nothing from your wallet.
