I would say most workloads benefit from SMT. I've done work disabling and enabling it and rerunning benchmarks to understand the impact. As a gross over generalization, disabling it can improve latency for workloads that are compute intensive. This is not most workloads, and almost everything will see some improvement and increase in throughput by having SMT turned on at lower utilizations. As you push the workload beyond 60-70% utilization the wins from SMT fall away, but generally are not impacting you negatively. What happens is your processor is over performing at lower utilizations, and your performance curve bends to where it would have been without SMT at lower utilizations.
