I love how easy pathogen (https://github.com/tpope/vim-pathogen) makes installing vim plugins from github. I always struggled with it in the past (and mostly avoided it) but now it is as simple as git clone and done.
Vundle is a minor but very welcome improvement on Pathogen, while Pathogen was a monsterous improvement on the painful Vim plugin management of before.
I too am a big fan of tpope Vim plugins, and Vundle is the first plugin that I've ever used to replace one of his with. So now I don't have Pathogen but I have a Vundle file that says "tpope" all over it. :)
What about plugins that are not in a git repo (but a hg repo)?
What if I don't want the lastest version of a plugin?
