From pages 1493-1494:
Similarities: baryon number is conserved in particle processes, and the 3 lepton numbers are each conserved in particle processes.
They are all fermions, with half-integer spin.
Differences:
Leptons have no internal structure, but baryons are composed of quarks.
There is only one stable baryon, but several stable leptons.
