They are pretty much the best real-life choice, for suitably broad definitions of "real life". We have yet to demonstrate superconductors that can operate at the required temperatures, but if you take modern high-T superconductors and say "like that only up to 350K" then you get very impressive performance.

Plasma sails, OTOH, require consumables, and I would wager that the concept proposals likely err on the side of optimistic specific impulses.
