I agree, overhead lockers are huge, too.

Although a lot of people here recommend the smaller and more intimate cabin, but so frustrating waiting for all the WTP and WT passengers to board. Often you'll get your welcome drink and have passengers standing in the aisle. When you disembark, you often wait for the main J cabin to leave first. Don't sit in row 5 either as it's close to the galley and the crew use the front lockers, even when you're trying to sleep and slam them shut each time.
