I have gotten excellent support here and don't even have a SUSE support contract. If you need immediate (and especially production level support) I would suggest going the official routes.
plus it keeps those that are actually contributing to the code, the masterclass workshops and the whole ecosystem fed so they can come here and help us 😉
also keep in mind that SUSE acquired Rancher Labs so like any changes in management and organizational structure there will be ongoing hiccups... but speaking of money, it's this acquisition itself that is also helps keep these awesome people fed.
