There is also the nice orderless package:

https://github.com/oantolin/orderless

It provides a completion-style which is very flexible and also
features initialism matching like flx. Internally it uses
completion-regexp-list + all-completions so it is very fast. You can
even customize individual components by defining dispatchers for
example I can append an equal sign to some input ("input=") to match 
that input literally or for fuzzy matching I use "match~" it is very nice.
