The comparison you saw was to square-rigged ships (think Mutiny on the Bounty) which did not go to windward at all well. There were some junk-rigged sailboats in the 1960s - the most famous was called Jester which did a number of trans-Atlantic solo races. The junk rig was quite easy to handle but had a lot of chafe too. Modern sail handling innovations eg furling jibs and mainsails and large winches have made 'regular' rigs much easier to handle and very efficient too.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
