5th Gen White 2 or Soulsilver?

Hello everyone, to start I would like to point out that I have finished every single Pokemon game including Black 2. My question is at the moment I only have black 2 which Im working slowly to complete my Pokedex.

Recently I have felt like playing a Pokemon game since I have done nearly everything I can in Black 2.(except catch em all) My question is should I get Soulsilver (I have all the legendaries from those SS and HG except maybe 2) or should I get White 2 since I already have Black 2. (My brother has White 2 so I can get all the exclusives anyway) But I would still not mind getting it so I can finish the game slowly while focusing on Black 2's Pokedex.
P.S I already finished HG and my brother SS back on release and we transferred the exclusive Pokemon and Legends upon Black and White's release.

All help on this hard decision appreciated. {XD}

What about getting and playing Platinum?

Maybe later, plus not my favorite Gen or region in my opinion.

I prefer White 2, although I do really like SoulSilver as well.

Rather unusual comparison but I'd be happy to help.

It doesn't matter if you have both SS and White 2. If you want to complete the Pokedex I'd recommend both games. White 2 is more interesting because of the White Treehollow situated in White Forest.

Get White 2 because that game have more good things then SS/HG or expecialy D/P/Pt

This is not really related to discussion of the Generation 5 games nor do I see anywhere it belongs. Please don't make threads like these asking what game you should get. If you don't know, ask in a Quick Questions thread in Gaming central.
