Seeing as this was an absolute banger, I did it properly, with some help from Claude to speed up messing around with scraping the Nobel website:
Which subatomic particle has produced the most Nobel prizes:
Electron: 10 directly associated
Neutrino: 5
Quarks/gluons: 5ish
Neutron: 3ish?
Proton: 2ish, more if you fold in quarks/antiproton
Higgs: 1
W/Z, Pion: 2 each
Tau: 1, but shared with neutrino
Technically 0 for muons
