Layer 3 Switch Upgrade - School Environment

Hi everybody,

Just wanted to bounce some ideas off of some of you in regards to layer 3 switching upgrades. Background:

*Cisco shop

*Elementary school environment, about 500-600 users.

*Replacing Catalyst 3750Xs. Looking for way more SFP+ ports, not just a direct replacement.

*Collapsed core. Our L3s handle both routing and aggregate fiber directly from layer 2

*Biggest consideration is latency, getting users to their web apps as fast as possible. Internet circuits are at other sites, so we're carrying Internet-bound traffic to/from those sites over Metro E.

*Reliability and stability is a more important than HA.

Some of our other buildings are using Nexus 3500-Xs at layer 3. I love the low latency and that's the option I'm leaning towards sticking with.

Any thoughts on the Catalyst 9500 series or Meraki 400 series? I know Cat4500s used to be the hot go-to for this use-case but I haven't gotten a chance to play with the 9500s yet. On the Meraki side, we're already Meraki at layer 2 and really don't need need to do any advanced routing at the sites we're upgrading, just participate in the OSPF process. Or any other models you guys or gals really like?

Thanks!
