Which canister stove simmers best for real cooking?

Across the reviewers we read, dedicated upright stoves with micro-regulators (notably the SOTO WindMaster) and the MSR PocketRocket 2 get the strongest simmer marks. Integrated Jetboil-style systems are widely criticized for poor simmer control, and most reviewers recommend them only if your menu is boil-water-and-rehydrate.
