If you did (dig into it yourself), you'd quickly find out that the urban myth about Zing somehow hurting latencies across the board is plain wrong. In fact, these days it tends to be percievably faster (in both latency and throughput) in about 70-80% of the workload we encounter. Certainly when compared to G1GC and CMS, and often even when compared to ParallelGC... E.g. it is typicaly >10% faster at things like Cassandra, Spark (TPC-DS), LMAX Disruptor workloads, etc. etc. etc.
