I believe Hive may be a digital synth emulation. Not bad at all, but if you are looking for a sweet analog lead, that might not be the one.
After trying the demo of Diva and Repro, I went Repro. Hard to find a synth with a better analog emulation than those 2. Can't go wrong with either.
The advantage to Diva is that it's not a strict copy of one synth architecture. You can mix up the oscillator and filter types. Repro is a straight up model of the Prophet sound. Which is fantastic, in my opinion!
