Should i get transformers wfc autobots or decepticons?

I recently bought wfc autobots but im more of a decepticon person but recently i started to like autobots but all my other TF games are decepticons so should i keep autobots or trade it in with some other stuff to get decepticons.Should i get transformers wfc autobots or decepticons?Why not keep both? If you use a second DS you can transfer playable Autobots to WFC Decepticons and vice versa, giving you all characters on both games
