Giant has a great reputation, and they make great bikes. Given the TCR's long standing reputation as a great race bike, I'd jump on a end of model year sale if I liked how it rode and I had a good local Giant dealer. I bought my Propel on an end of model year deal, and considered a TCR. If I lived in the mountains I would have gone TCR.
