Vortex Sound Research

Would getting both of them be redundant in a small size rack (a Mantis)? I am aware that they are doing different things, one is a resonator, the other is a resynthesizer. But at the end of the day I will use either as a way to run a dry sounds through it and change them up into something more interesting, whether it will be by having it pass through a resonator or be resynthesized. If anyone has experience with both (or either one), I would appreciate some advice! Also Panharmonium is veery expensive in terms of HP, a whooping 26HP, so that’s another thing to consider
