For serious polyphony, I reach first for my Access Virus TI2 keyboard hardware synth that gets me the best all around results quickly with dozens of voices, effects and filters. Sort of like modular in a box. I do have a couple of eurorack polyphony modules but getting them patched and sequenced to make lovely trance chords is sort of a pain and far more of a rabbit hole challenge to sequence in modular than my Virus. You still need a good complex sequencer like Vector 512 and a filter bank, polyphonic eurorack module(s) and mixer.
