I use the butterfly hank method, it's a really neat way of keeping cordage tidy if you then put it in a bag.
However it kept tangling up when I tried carrying a hank in my pocket.
So for paracord I rig up a sort of grenade shape for quick deployment see vid below

I also carry spare paracord as cobra braid lanyards, very neat but not quick to deploy.
For thinner cord like bankline I have two methods - I either double it and then make a simple slipknot - daisy chain for easy deployment then use it as a lanyard.
Or recently I used the bankline like whipping on an aluminium canister on my keychain - finishing it off with some half hitches. I prefer this approach as the cordage is much straighter when deployed and also you can store a lot of cordage for relatively little space, turning the outside of the cannister into a reel. Pro tip - A drop of wood glue on the end will keep the cordage from untangling until needed.
hope this helps
