Depends on your choice. At sonic unleashed WII/PS2 version is sonic colours surely better. At sonic unleashed XBOX360/PS3 version it depends on what you like, the most will like sonic colours more where it's more based on speed. At sonic unleashed you have a lot of werehog stages which are slowly and in my opinion very good, but doesn't fit in a sonic game. This is just an opinion of me, maybe you think different about it so to find that out you can watch some gameplay movies on youtube. ;)

There's a lot of places to get it. If you go to Youtube search Blitzsonic or (sonicblitz for Unleashed version) and on some of the videos you can find links to models, levels, and the Sonic Blitz Engine itself
You have to find the right shoes. They're in Shamar's Entrance Stage.
Go down into the Spangonian sewers and you will find a record. That is the Endless Possibilities track!
You get them from Spagonia in the Gaia Gate. Explore a bit and you should be able to find them.
It is not possible to download Sonic the Hedgehog comics for free legitimately. You might be able to find some on eBay.
For a video walkthrough you can try going to Youtube and typing "Sonic Unleashed walkthrough". You might also try game sites like Gamespot or IGN. For written or more indebt walkthroughs you might want to try the ones at GameFAQs.
A good place to go would be soniczone.net or find a youtube hack.
