I tried Ricera rice yogurt.
I bought vanilla because I figured it would be good ... same flavor as rice pudding. This stuff has a disgusting, mucose-like texture. The flavor wasn't good enough to make up for it.
I've also tried Almande yogurt with almond milk
The cherry was fine, but it was more like a gelatin dessert and not yogurt. The taste was really light.
I tried a number of soy yogurts ... sorry don't recall which ... and those are closer to dairy yogurts. None stuck in my mind as being super delicious.
