Sasaki's daifuku is one of the best in Toronto - plump, flavourful, and just the right level of stickiness. Plus they have a good variety (my favourite is the cream one).
That said, I haven't been impressed with the other stuff I've tried. The matcha tofu cake was a bit bland and the macarons were a bit too dry and crumbly.
Overall a 5 for the daifuku and a 1-2 for the other offerings.
