Vortex Sound Research

Hi, which one as main mono synth for a beginner ? About hardware, i only use a Volca Keys, and for polyphony i have the TAL-U-No-LX... and i love that juno vst emulation !

Now i want a cheap bass/lead desktop synth, Model D was my main option but now there is the Pro-1 too. What do you think ? A pro-one or a minimoog clone as a first "real" monophonic synth ?
