Wing (and, by extension, 00) was a fine watch at 10, and G probably would have been, too. They're considerably less fraught in both iconography and philosophy than some of the other series, and quite a bit more hammy. The Build Fighters/Divers series are great, too. Stay far away from AGE, though; cutesy stylings because it was intended to exist alongside series like Yokai Watch, but it ended up being quite problematic.
