On the edge, blu is in a crowded hallway- so unless you get a good table away from the hallway- not so pleasant. You also have an infinite balcony- like a regular cabin with a few "perks". The regular cabins have access to three restaurants- you can rotate which is great and each restaurant has slightly varied menus, for example one has a greek theme. I was in a Sky Suite and mostly dined in suite dining room and specialty restaurants, but the concept of the three dining rooms was great. They are much smaller then the ballroom type dining in the regular dining rooms.
We still prefer the suite deck and lounge on the edge class ships- and the extra space and storage nice
