I own an 1971 Ranger 26 - and love her - but I've sailed 1000s of miles in a ketch - a Pearson 42. It does have more lines than a sloop, and the mizzen is something of a pain to flake and cover - but I like the rig.
It is much better balanced in heavy weather than a sloop. We'd usually sail with only mizzen and genoa - the genoa reefed (furling rig) when needed. We'd only raise the main in light winds.
Even in heavy winds, it was a well-balanced rig, mizzen and genioa - without the excessive healing one often gets in a sloop.
