DS9 has episodes like Move Along Home which is one of the worst Trek episodes ever in a good Trek series (only the last one of season 2 of TNG is worse tbh), but then you have episodes like Duet, In The Pale Moonlight, Far Beyond The Stars, Once More Unto The Breach, and The Visitor, to say nothing of the super hardcore ten-episode arc that rounds out the series. But they also do silly episodes here and there that are still really great, like Our Man Bashir, Trials and Tribble-ations, and Little Green Men.
