Speech synthesis by concatenation does produce more natural-sounding results, at least until you notice its quirks, so casual users tend to prefer it. But I know some heavy speech synthesis users, specifically blind programmers and power-users, and they tend to prefer parametric synthesis, because it's more intelligible at high speeds.
