I’ve got a Vermillion which I use in an FR66s arm; it’s a really nice cartridge, very holographic, great dynamics, excellent tracking and minimal edge or nastiness to the sound.
Compared to my other Koetsu, a Jade with diamond cantilever, I’d say the Jade has a more “authoritative” feel. With the Jade you get the same as the Vermillion in terms of all the things listed above, but there’s something more explosive and solid about it (in a good way :)). One thing that is palpable is the lower frequencies with the Jade, the bass is really good, the best of all of my cartridges in that regards. That’s not at the expense of midrange or higher frequencies , just something that really stands out.
