I originally started with Johnny.Decimal for my life and after giving it a big try, switched to PARA.
J.D is fine (maybe even great) if your categories are relatively static, such as a small business, but as an individual, I found it very restrictive and challenging to remember. Moreover, while the decimals are cool, I found them somewhat irrelevant if I was the only one referencing them.
J.D is optimized for retrieval, where what I needed was optimized storage, and then occasional retrial.
To each their own of course, and using any system is better than none.
