Table and chair are more comfortable in most cases. Especially for us more rotund types. Many folks I know wont have a booth for that reason. Now if your just on vacation weekending the storage and sleeping capacity may be more important,
Your talking about a "J" lounge? Not a pull out" chair" but a section of the couch that pulls out to form a L when the slide is out ? Nice for Tv watching depending on the tv placement but I've sat in one, flexsteel, at a show for a hour with a salesperson .. it was ok. not as comfortable as just the couch ..less padding maybe.
