[Star Trek] How can it be that every Holo-room can create more emotionally convincing personalities than Data ever was?

Those personalities were driven by conversational algorithms, tailored to present convincing facades within scripted scenarios. They were not inherently sentient, but non-self-aware bots puking out pre-drafted dialogue and pulling, when needed, from banks of text (and body language, and scenery) which looked statistically relevant. Given the leisure time and desire for recognition that drives the lives of most Federation citizens, many holodeck scenarios have been worked on for countless hours, to the point where the illusion of interaction with sentient beings is nearly flawless. 

But at the end of the day, these aren't real people with real feelings, and the things they say aren't being motivated by anything but an instinctive reaction to stimuli provided by holodeck visitors. Data is something entirely different- and wonderful.
