If you read posts in this forum you'll find very strong opinions about which is better. I love my TA and didn't consider the SM. Someone else will give you the opposite response. SO, what you need to do is go look at the bikes, sit on both, if you will have a rider (like my wife) - have them sit on both, and see which YOU like best. They are more similar than ever in 2007. Both are great bikes. Pick the one that appeals the most to you.
