Well, for one thing, our Standard Model of particle physics would have
a lot more problems...
If there was only one grade of lepton, then we would have four families
of quarks but only one family of leptons, which would quite succinctly
destroy all those beautiful multiplets that Gell-Mann thought up.

Moreover, we would lose several parameters in the QED Lagrangian,
ratios of particle to particle mass would no longer be coherent, the
CKM matrix would most likely not exist..

The list goes on.
