I think the Smart 7 7000 may be the better deal, as it also has advanced features (6 brushing modes, lithium battery, bluetooth and a similar motor I believe) and is discounted by more. It comes with 2 brush heads.
The Sakura Gold Limited Edition of the Genius 9000 comes with 3 brush heads and a travel case.
Do not forget cashback to bring the price down even further.
