Issue:
State Variants Priority Order
## Foreword ##
People are (or at least, I am) increasingly excited about the possibility of having everything they need out of the box thanks to Tailwind, and state variants are a vital part of building user interfaces.
Tailwind already supports a bunch of them, but new ones are always proposed and discussed (see #136) and, as time goes on, they may get introduced as well.

## Purpose ##
There is a problem though: since Tailwind does not rely on `!important` 
 rules to override styles, the output order of the state variants becomes crucially important.
It's true: users may tailor their code by implementing priorities by themselves and fit their needs!
Good defaults, however, could save a lot of headaches and work.

That's what this thread is for: discuss better state variants priorities.



Discussion:
## Hover vs. Focus ##
Currently, hover has a higher priority than focus. However, as discussed in the PR #379, this choice has his pros and cons.
As it is now, buttons have huge benefits, whilst inputs may lack consistency.

Are you relying on or fighting against this order?
