CAVEAT: as I don't want it to seem like I think a CAAD or other AL bikes are crap. They aren't! They just don't have the ride quality of a Peg....which is what the OP was asking about.
If I were on a more limited budget and had say $3k to build a bike out of: I'd be perfectly content riding a CAAD with C12 and some handbuilt wheels. I would have zero issues if this were my one and only bike. With the new allowance for fatter rubber, many of the jarring ride qualities are absorbed in the meaty rubber.
