No need to have two plugins that do the same thing, CtrlP does buffer switching too.
While we are at it…
I never really used TagList or equivalent widgets in other IDEs/editors as an outline of my code but rather as a navigation tool. :CtrlPBufferTag is great for moving around in a large file. Same thing with :CtrlPTag for navigating a project. I love CtrlP.
If the "you" is me you don't need to convince me at all: I'm a diehard Vimmer.
As others have mentioned for fuzzy finding, use CtrlP. I also use FuzzyFinder for quickly switching between many open files (buffers).
