Ironically by the end of the 2 era, Miku wasn't as HQ as it was near the beginning. Miku didn't pronounce many vowels sounds without slurring or chopping them up. Her V3 is better quality overall then her V2 design at the very least. Many of the later V2 (not all of them though) could do better. But this is not something against Miku, its just experience and improvements in technology over time lead to those little improvements over time that lift a vocal up some quality over others.
