I personally have not owned either... BUT... I have asked the same question to a lot of people.

A friend has had tein basics, omni streets, and form/functions. He said that for a street set-up he liked the form/functions, and he was very UNHAPPY with the tein basics. However, he did say that he thought the omni sports would have been stiffer than he would have enjoyed on the street.

Hope that helps a little.
