PD does more stuff. The dataflow model takes some getting used to and tends to linger in the background even if you get down to the libpd level.
VCV/Eurorack is a simplified rather dated synthesis model for people who don't want to go that low. It's ideal for people who just want to noodle around plugging and unplugging things and turning knobs.
I've been sketching ideas for a next-gen synthesis language which is more powerful than PD/sc, keeps some elements of modular thinking, but adds some useful creative extensions.
If I'm really lucky I'll find the time to do something with the ideas in the new few years.
