Meraki is owned by Cisco and I often wonder how long it will be till Cisco tries to merge them and destroys them in the process.

Right now, I'm pretty happy with Meraki though my exposure is limited. I'm supporting MX450s in DCs and MX64/Z3 in homes, and we've recently started using their wifi.

They have the issue of most GUI stuff in that it's hard to get info out of them.
