Wasn't it worse fuel economy (lower ISP) but higher thrust?

  No, this would be heating the propellant to higher temperatures than chemical reactions can get -- in principle one could get much more than 50% extra ISP for the same propellant mass. In rocketry/satellites/deep space propellant mass is a big deal -- anything you can do to reduce the amount you need without having to gain even more mass in other ways is a big win.
