Command shifters work great and are reliable, but are really only optimized to work with Suntour Accushift derailers (and Suntour Alpha freewheels for the 7s levers).
The rare 8s variant can be used with an otherwise Dura-Ace 8s setup.
The Command levers having the cast alloy mounting pod are considerably more rigid and were the higher-end offering.
