I went from a Fatboy to a SG. I was looking to move up but didn't want a full dresser, I wasn't ready to make such a bold move. Then I saw and rode the street glide with its aggressive looks and what I think is sporty handling. I traded my 07 FB for a 09 SG then a 10 SG and now a 11 Krypto SESG which I absolutely love! I still miss my Fatty (mostly because of the color) but to me the glide has so much more to offer, radio, cruise, antilock brakes, killer looks and a ride you cant even compare to a FB. I love riding mine, love the looks and comments on my bike, I am very biased of my Krypto and plan to keep it for a couple years. BUT I am going to Sturgis this year and will be checking out the 12s, soooooo we will see.
You have to follow your gut instinct, take everyones comments with as we say "a grain of salt". In my opinion you cant go wrong with the SESG.
Good luck
