Same. I had quite a lot some time in the past, but also made the "using vim on some foreign machine and being confused as hell" experience by trying to use hotkeys or commands that didn't exist. Also just keeping the config synched between my own hosts was more annoying than I anticipated. Not to mention resolving conflicts between different plugins, or random stuff breaking when updating anything.

Nowadays I have a vimrc that just tweaks vanilla features the way I like, plus some highlighting for certain keywords regarding a C codebase I occasionally work on. The only plugin I use is a modified version of DetectIndent.
