Polyphony on modular/eurorack is getting easier. I have an Acid labs Chainsaw polyphonic module on order and will try it out.
That said certain styles of music like trance and house are easier with a polyphonic fixed hardware synth like a Roland Jupiter X or Prophet X since they have 10 voices, filters, arpeggio, sequencer, FX and even drums on some Roland synths included.

Exactly, fixed hardware synths are certainly better for some applications, but polyphony in eurorack is not that complicated or expensive anymore. The different way of controlling them can be a bit limiting in some ways, but I would argue that that's also inspiring. And with modules like the polycinematic, we're getting closer and closer to having something very similar to fixed hardware poly synths in eurorack too.
