Ctrl+P is a bit more "fuzzy finder" than ido-mode. It fuzzy finds paths under the current directory (or up to a project root if there is one above your current directory, though this is configurable). You can switch between "find in filename" or "find in path".

I've grown accustomed to it, but it's not the end-all-be-all. For example, I can type exact filenames in some work repos and get matches that are not for the file I'm looking for because the fuzzy finding is too fuzzy and starts hooking in matching from the directory structure in the path.
