Preferred sailing waters in the Age of Sail

Which waters did sailors consider best during the Age of Sail?

The Mediterranean and Indian Ocean were often favorable, though getting to the Indian Ocean could be extremely difficult.

Reaching it from Europe, however, meant a difficult and hazardous passage. The answer distinguishes pleasant operating waters from the logistical and navigational challenge of getting there.
