We have been deploying the ASR-920-24SZ-M.

We had considered the 2-port and 12-port options to reduce cost, but
since Cisco can license the number of ports you activate, it's better to
take the 24-port unit and turn up the ports you need over time.

I've never deployed anything smaller than the 24-port, but I suspect
they all operate the same. It's the same chip they use in all models.

Remember that the chip is rated at 64Gbps. So if you add IM modules,
you'll oversubscribe it in the larger models.
