I have the original tiani and the we-vibe 2 and 3. I prefer the we-vibe 3 as it is stronger and vibrates on both sides evenly, something the tiani doesn't do. I like how both the tiani and we-vibe 3 are remote controlled but find tiani more glitchy and don't know what to do with the vibrating controller.
In order of preference:
I would like to try the Tiani 2 to compare.
