How are we feeling about MS390 switches these days?

About 9-12 months ago there were numerous threads discussing reliability issues with the MS390. Since then it appears that Meraki created different firmware for these separate from the rest of the MS line, and I haven't seen quite as many posts about the MS390 as of late.

We're looking at a use case for a new location that will have 6-7 IDFs, each with dual 10G fiber uplinks to the core, with copper uplinks to a (non-Meraki) upstream firewall/router. We've standardized on the MS250 at the access layer, but with only 4 SFP ports per MS250, we'll likely need to stack too many switches together to get the fiber port density we need.

An alternative I was considering was leveraging 2 MS390-24's stacked together with 8x10G uplink modules in each to get us the fiber port density we need. The only other option I could think of was the MS425 but Meraki's site isn't super forthcoming on whether or not 1G copper SFPs are compatible with this model for our uplink port needs.

So is the MS390 more reliable these days? Should I look at that, or consider one of the 'traditional' MS switches instead?
