Well, the IPIP-NEO isn't as accurate as the NEO (or the MMPI), but the fact that you found it less accurate does not necessarily mean that it is less accurate. Personality inventories measure your personality, not your perception of your personality.

Personality inventories like the NEO have considerable data both backing up their predictive validity (predicting behavior across different situations), their stability (people score the same across 45 years), their heritability, their utility in clinical settings, and their overall construct validity (personality appears to be 5 dimensions).
The Myers-Briggs typology to which this test (similarminds.com) is related has very little data at all supporting its validity. (It still may be fun and interesting to take though).
