IMO if you actually want to know for personal use, the question's way too broad. (But fine for a discussion many can benefit from of course.)

The more specific they are (to something you care about) the better.

Unless they're so general that there are high-quality talks about a range of things I suppose.

Agreed, that's what I'm looking for, specific events. What's an event that is worth going to if you're investing hard in Kubernetes? Azure? Devops(broader scope, but could be usefull). Development in general is harder since you could say it's language dependent, but a broader event like "The Developer's Conference" is fine for this kind of thing
