I know the 5500 series 105 group was basically an version of an old Dura Ace.
I don't understand what you are asking. Is one better at...what...exactly. Regardless of price I have yet to find Shimano components that did not do what they were designed to do for a long time.
Are you comparing new Sora to used 105? Or are they both new.
