Yes, it is stable enough that process doesn't crash. Sometimes process lags behind quorum due to maybe I/O issues. But overall, current node I am running is stable since last 1 week. There are a couple of problems I faced when process abruptly shuts down, and I will be opening issues for those. But those problems are not due to resource constraints.
Of course, I will not recommend it for production use. If you have a project (in testing phase) which constantly needs to hit SDF horizon, then this is a cheaper option to set up your own core/horizon instance (than spinning AWS instance).
