> Katakana is used less than hiragana

Katakana was used much more frequent than hiragana for about a century following the Meiji restoration, regardless of the technical limitation. That can be thought as another parallel though: Latin majuscule letters are (close to) the original Latin script while minuscule letters are derived from them, but now minuscule letters are much more frequently used. The only difference here is that either hiragana or katakana wasn't derived from each other, they share the single origin of simplified Chinese characters.
