In our experience, this strongly depends on the services involved, as well as the scale.
For example, for our own service: If you have a hundred or two hundred licenses, you can drop our system on a linux box and usually you have to throw a yum update and one or two service restarts at it every few months and it just works. I honestly wouldn't be surprised if many of our small on-prem solutions have better uptime than the SaaS clusters, or be capped in uptime by some externality, rendering the system downtime irrelevant. If their VMWare cluster is down, our system is down, but no one cares.
This also mirrors a lot of our internal systems. At a small scale, you can just dump chef, jenkins, sonar, nexus, whatever on a linux box and forget about it.
However, this changes with high license counts. We have singular customers in our SaaS offering that are more than 50 - 100x bigger than the small on prem systems. At that point, our SaaS offering is better than anything the customer could to on-prem. I'm confident to say this about all of our customers, except maybe 2.
