I use buffers and splits.

My work session has about a hundred or two "open" files in the buffer, and I split and un-split windows often so that I can view multiple files at once.

But my most common way to change current file is :b <first few letters + tab complete>

I occasionally prune my buffers for files that have been deleted, but it's mostly unnecessary to. When I close it, I just save the session in a file and re-open the session.
