Help with word choice

Hello, everyone.

Two persons, say, are justifying their respective choices for choosing a language to learn. Person A justifies his choice by the fact that hundreds of millions of people speak that language, whereas B argues that, and although spoken by far less number of people, the language he choosed gives access to a rich culture and wealth of knowledge that's characteristic of the people of that language.

Now, if we were to describe Person A as aproaching/looking at the matter from a quantitve point of view, does it mean that B is looking at it from a quality point of view?

I don't think quality is the word.. . What do you think?

Thank you.
