Only более is used to form the superlative of adjectives and adverbs. Он более грамотный, чем его сестра.

In the meaning of “in bigger amount” or “to a bigger extent” we use both, более being more bookish. (What is the synonym to bookish?) I hardly ever use более in this meaning. Добавь больше муки в тесто.
A synonym for bookish would be "erudite". It's not a word one often hears spoken, though; however, when I was young and in school I was taught by a teacher that valued a rich and comprehensive vocabulary, and passed it on to her students. So that comes easily to my mind. Does anyone else think of another word that would convey the meaning?
