^ That's great you enjoyed Tsubaki's route like this.
I personally ranked it the second best (just closely after Haru's) but I'm always wondering if it was because Tsubaki never bothered me (despite her archtype might revulse many for being too... "perfect" "airhead" etc... a bit like Nagisa in Clannad).
That said, her development is huge, perhaps the biggest among the heroines.
Gonzou is... the grizzly (
) but unfortunately not as awesome as Sharin's Houzuki.
As for Kanon... that is... really difficult to say.
For starters, Kanon's route just sidetrack completely Maou's matter. However, while in Tsubaki's, it was just on the background and Haru was still on his track, in Kanon's route, the reason is lame.
It really depends how you are fond of "family" drama, because Kanon's route can be considered as the worst or as ok/good. But generally speaking, the setup of this route is really awkward.
