One word: scale.

Descent's world was all tunnels and closed spaces, thus relativly easy
to render.

Quake's world is a lot of open spaces (there are some places that allow
you to see right across the level, which can't be done in Descent.

That is the biggest difference.  Also, Quake's entities and rooms are
much more detailed than Descent's.
