Which CD should I buy?!?!

I’ve been thinking about buying a sonic audio cd for my collection, but I’m having a serious problem picking between 2 options…

The 2 sonic adventure 2 multidimensional cd’s (+original soundtrack disc), or the 4 sonic 06 soundtrack cd’s

The SA2 discs and front covers look amazing presentation wise, and each cd has amazing songs. However, sonic 06 had THE BEST soundtrack out of every sonic game hands down.

My problem is that I’m all about vanity, I would much rather have the SA2 cd on my wall due to the fact it LOOKS better, but I would rather listen to the OST of 06

I only have one spot left on my wall where I keep my cd’s I need help!!!! 🙁
