same here - works great and never needed anything else.

Same. I love vim and have no plans to leave, but I have no interest in being on the upgrade treadmill when my current system isn't broken. I've also had plugin updates break stuff, and it's a simple rollback in git back to a working state. I'm not sure how hard that is with these various plugin managers, but it's quite simple with git and I don't have to learn yet another tool/way of doing things.
