I have both. I use neither. :p

Why not?

Mining world is pvp, and exp is worthless, so nether is a waste now.
Aether COULD be awesome if andrew resets it, but as of now its like what happens when a carnival gets abandoned. Lots of cool stuff, not a soul in sight.

 

me and my two cousin just got a ether and think it is awesome! Join us rabid we can make a huge waffle :D
