Yes the TT01ED is the better value of the available type E chassis's for the price. However you cannot go wrong with the TT01R type E as it has all you will ever need in a TT01, although it does not come with an esc or body.
The ED only comes with drift wheels so if you will be racing you will need to purchase the wheels of your choice (or as per rules of your race series) in addition to the kit.

Note that the standard old type TT01 bearing set is no longer available and the type E needs to be used. All bearings are the same size except that the type E includes 4 x 850 bearings that are used in the newly designed steering arms.
