I drive both (1.3 version) and would never touch myvi anymore...
Iriz far superior...
not sure how 1.5 Myvi vs 1.6 Iriz though....
1.6 Iriz manual not out yet. So only choice is 1.3 Iriz Manual or Myvi 1.5 manual.
And personally I dislike the Myvi for various reasons include owning 2. So Iriz for the win!
