Pro Loosely coupling allows for lots of flexibility
Aura is a loosely coupled collection of independent libraries with no base classes. This allow for extreme flexibility in choosing what libraries are needed.
Pro Uses static methods

Pro Open source

Pro Filters
A unique feature of Flight is something that the author calls filters. Filters are functions which can be executed before and after any other function and can change the parameters and the output of said function.
This feature is used instead of hooks which in other frameworks are used to execute code into different parts of the application's life-cycle.
Cons
Con LICENSE
Con Small community
Aura's community is still relatively small and it can be a little hard to find help or guides if you get stuck somewhere.
Con Cannot use ArrayAccess
The fact that it uses static methods means that it's impossible for Flight to make use of ArrayAccess, which in turns means that it cannot inject dependencies easily.
