The pattern that has worked out really well for me, is to just organize my data into specialized collections, and not worry too much about the underlying filesystem. I can't believe how much trouble I went through trying to find the filesystem that could do everything. I mostly use git-annex, and various tagging systems, or just git repos. Now my data is much more portable and flexible. None of these tools are perfect, but I'm using tools that are mostly good at the job. Whatever problem you are trying to solve, you probably don't need to solve it for your entire filesystem.
