I don't think I've ever been limited by jq's speed, but good to know there are alternatives if it ever becomes a bottleneck.

Other than that I can't think of a reason to use this over jq; the query language is perhaps a bit more forgiving in some ways, but not as expressive as jq (and I've spent ~8 years getting pretty familiar with jq's quirks)
