Personality does not equal emotions. Emotions stem from how a personality reacts from things, like a bad situation for example.

Ultron might see emotions as a flaw, yes. What's to stop him from thinking they're good, however? And if you want Vision to have emotions, make Ultron unemotional, like the original comics. Vision is the counterpoint to Ultron.
