Others have answered well, but I think there's something missing.

It's not applicable in this case, but one other major thing to care
about on JNPR kit is that the ports share the same PFE type, for example
on MX mixing between DPC & MPC within a LAG is a bad idea, same for FPC3
vs FPC3-ES on T640/1600. They might *work*, but you're likely to
eventually run in to some ugly edge-cases.
