What's your opinion on Guitar Hero III?

Like others have said, PS3 is the best option. The Sony exclusives are amazing single player experiences, and at least in the us they are quite affordable. For example, uncharted trilogy is like Indiana Jones, with the second and third games being amazing, Last of Us has an amazing story and gameplay, and God of War 1 2 3 are really fun to play.

Also, you have a large catalog of non-exclusives. My favorite single player campaigns are Bioshock, Call of Duty Modern warfare (1,2,3), COD Black Ops (1,2), spec ops the line, red dead redemption, and GTA V.

I buy physical to get better deals. Steam sales are a lot better than most digital store sales, so for consoles most of the time it's better to buy a secondhand copy than try to wait for a sale. Xbox and Sony do have good store sales, and I use them when I can, but especially Nintendo their games are full price years after release on the eShop and at retail.

Just look at deku deals for Mario Odyssey for example, where the physical all time low was $30 while digital all time low was $35. I got it for $20 a while ago used. I wish we had steam on consoles.
