Spore is definitely more innovative game design, while LBP allows more creativity from the actual user.
The ideas in Spore are amazing and I wish I had a computer that could run it decently so I could try out what could be the first game of it's kind.
LBP on the other hand is more of an idea that has been done, but now trying to bring that idea to a more accessible level that everyone can enjoy.
It's kind of like how Nintendo didn't invent motion control, but they made it fun and accessible to everyone with the Wii.
All that said, the only reason I'm looking forward to LBP more is I don't think I could run Spore.
