jq feels like a much more robust tool than yq. I understand that the task of processing YAML is much harder than JSON, but:

- yq changed its syntax between version 3 and 4 to be more like jq (but not quite the same for some reason)

- yq has no if-then-else https://github.com/mikefarah/yq/issues/95 which is a poor design (or omission) in my opinion

So yq works when you need to process YAML, it can even handle comments quite well. Buy for pure JSON processing jq is a better tool.
