Antimatter was fairly good, as I recall, but its premise was a bit odd. The idea that Bajor was setting up its own shipyard to build Starfleet vessels as early as season 2 seemed like a stretch to me even at the time, and even more so in retrospect. Also, the idea that antimatter was a rare and carefully controlled substance and that there'd never been any on the station before was kind of strange. It would've been a plausible idea in isolation, but it didn't quite fit what was established elsewhere. I guess Vornholt didn't read the technical primer that was provided to aspiring writers for the show, since it said the station's fusion reactors were spiked by minute amounts of antimatter. The later, mass-market DS9 Technical Manual abandoned this idea (along with the bit about the power transfer system being microwave-based wave guides and one or two other early details), but what about photon torpedoes in the weapons sails? What about all the warp-driven ships that had docked at the station over the years, or that were stored aboard it, like runabouts?
