Everyone camps/RVs differently. For me it's an absolute must have. When I get older and my kids are grown I may find myself doing less camping and more RVing and it may not be so important.
By far the best feature is the outdoor sink to be able to wash hands while cooking. The electric only fridge is pretty useless and I just replaced it with a cooler.
I also like to have the space outside for storage (cabinets, counter top, etc.).
There's really no right or wrong answer. It just depends on how you use your RV.
