I'm going to go with Tsutarja on this gen, I'm thinking. Mijumaru looks like it has too much going on for me to take a liking to it, but it's evo looks more... developed, structured to me. It looks like I can kind of tell where it's going, and it looks like a good direction. Pokabu looks cool, too, and I'm dying for an evo leak so we can determine which direction it's going (unlike the disappointingly unclear Tsutarja evo.).
Overall, this is shaping up to be a good generation for the starters!
