Doing better than me. Only inertia keeps me on Appveyor. Once I have time to look into Azure Pipelines, I'm off Appveyor for my Rust projects.

At least for open source, Appveyor builds are serial (across all of my projects?) and you have to (had to?) go through hoops to setup cron triggers.

For serial builds, it is so bad, half the time I give up waiting and just submit.

For cron, I only care about scheduling about once a month or so to double check none of the tools I rely on break so contributors aren't the first to see them and have a negative experience.
