I use CVS, RCS and Subversion on my personal projects for several years before I learned git. I don’t remember any of them being a pain to setup for small projects and Sourceforge provided free CVS hosting for small projects.
After that I used Subversion via TortoiseSVN for Windows, which was quite nice to use, though I don't really remember much of the details... I do remember asking myself why everyone was moving to git when "perfectly good" source control already existed, but after 10+ years on Git, I think I was wrong and we did need it, we just didn't know it yet.
The fun/frustrating part was getting branching and "views" correct.
I worked at an organization on this side of the century where it was one person's full-time job to handle merging code from different teams. The same organization didn't actually use raw Clearcase either -- it was wrapped in hundreds-of-thousands-of-lines-of Perl scripts.
In Git, I can just create a local repo for anything, and I don't have to decide where I want it. I could never push it anywhere, or push it to a private hosted repo to collaborate with a person or team, or push it to a public repo to open-source it, and change between any of those at any time. I don't think you can really do that with these hosted systems. You could spin up a local CVS server if you really wanted to, but if you later decided you wanted to open-source it on Sourceforge, don't you have to abandon the history and publish it there as-is?
