Perfectionist is about wanting everything to be perfect in all areas. A fastidious person cares about neatness, while a perfectionist might struggle to finish tasks because nothing seems good enough.
Can fastidious sound negative?
Yes, it can. While being careful and thorough is good, being too fastidious can make you seem picky or hard to please. How the word comes across depends on how and where you use it. Context matters a lot with this word.
