Authors that exemplify both quality and quantity?

We've all heard the adage: Quality over quantity, but in the vast landscape of fantasy writing, I was wondering if perhaps there's a select few out there that actually produce a considerable amount of work that's consistently top quality. This is mostly my excuse so I can look into those authors and see if I can find a new series to lost myself into lol

The first example that springs to my mind is Steven Erikson. Erikson wrote the complete Book of the Fallen series without stops or gaps across a decade, writing huge epic fantasy novels that average 300k words each, and he wrote different spin offs and novellas in between without breaking his pace. And above else, Malazan is often ranked as one of the most complex and consistently-great series out there.

What other such examples are there?
