Recent versions of zstd definitely don't obsolete LZ4, or else I don't think the author would still be contributing to both... zstd also seems to be optimizing much more, recently, for the large stream of data use cases, versus the fixed-size or smaller records you might get in, say, databases, or filesystems, so I think it's actually becoming less generally useful over time of late. And if you're going to play with Snappy, you might find S2, which was linked on HN relatively recently, interesting.
