Determining the absolute 'highest ranked' nail polish is subjective and depends on the criteria (e.g., longevity, chip resistance, color range). However, some consistently top-rated nail polishes include OPI, Essie, and Dior, known for their quality formulas and wide color selections. Consider reading customer reviews and expert beauty publications for specific recommendations based on your needs.
