As you can see, there is no right answer. How you plan on using the RV is going to have more to do with what works for you, than what anyone else thinks about theirs.
For example, in reading the comments, I can say that: 1) positioning of a TV is a complete non-factor for me (I don't have one in my RV and don't want one); 2) I'm not willing to go 3+ ft bigger to get a walk-around bed; 3) my dogs don't need all that floor space as they are usually on the couch with me (both are 85lbs) - just like they are at home when there is space; 4) I'd rather have a smaller floor space than deal with a slide; 5) If I want extra space, I go outside; 6) Being organized is a natural thing for me, so it isn't any more difficult to do things in a small rig than in my own home.
