That is not true. I have a resin printer that is around 3 years old (Anycubic Photon Mono M5s) and it has a level of detail that simply cannot be matched by injection molded parts. I have printed some miniatures that have details much smaller than a human hair, like the needle of a syringe in 32mm scale.
Once painted, the figurines are indistinguishable from non-3D printed ones unless you pick them up (they're heavier often).
That said, the article is still right. Resin printers are a massive pain. They're highly toxic, and the time spent preparing, and then post-processing is quite high, but also stressful because of the toxicity. I use my filament printer almost every day, but my resin printer has been collecting dust because of this.
