i did the reverse as you, the shure E4 ent back and i ate the restocking fee - and i stuck with the triple.fi's and it was an easy choice.
at the most basic level i can say the e4 sounded like it was jamming the music into my ear while the tf10 kind of sat back and pushed it in my ear. e4 mids were so forward and bass a bit anemic that it felt thin and the music shoved in not delivered properly. the tf10 with what people call recessed mids has a nice soundstage for an IEM.
