Black 2 VS White 2

I prefer Pokémon Black 2's Shiny Gible but I bought White 2 to tie in with my original White. It really depends on your Pokémon preference as to which you like better, the storyline is the same in both, therefore the version exclusives and the aesthetics are basically the only things that differentiate the two.

 

Lilligant isn't catchable in Black 2, so it wasn't worth it.

That, and Once a week, you can get a Hidden Ability Braviary in White 2. Nothing is more 'Merican than a Defiant Braviary.
