The fruit gelatis I've tasted have been pretty amazing. Mango is incredible, watermelon is great, the boysenberry was delicious except I would have preferred the texture if the seeds had been strained out. The jasmine is really interesting, though personally, just a taste was enough for me, it's pretty strong.
The soy flavours are really nice, and it's great to be able to actually have creamy ice-cream flavours, but yet at the same time, they're not quite brilliant. The bacio tastes almost like nutella, and the pistachio was pretty nice too, but they just have a bit of an aftertaste or an edge to them. Looking on the website, their soy flavours are also sucrose free, so I suspect it might be the artificial (or natural but not sugar) sweetener.
Overall though, I highly recommend it, whether just for ice-cream, or if you want dessert after having dinner with omnis on Lygon St somewhere that doesn't do vegan sweets. IMO though, you're better off with the fruit flavours than the soy ones.
Cons: Not every flavour is vegan, The soy flavours use non-sugar sweetener
