Obviously a personal choice and lots of opinions. I largely agree that a 5th is favorable for staying put and a class A is best for moving lot. At least for the way I live/camp it is. Of course, everyone is entitled to their own opinion.
Class A is much better while rolling down the road - visibility for seeing sights is better, on board generator can be fired up to use microwave, etc. Slides are less restrictive to allow for movement while retracted, spouse can take bathroom runs while in motion.
5th has a better floor plan with more usable space (no steering wheel in the living room, deeper/more slides), 5th and truck will likely cost less than a class A and toad. Most 5th wheels have more/better storage.
Again, we all have different opinions and usage needs so your opinion may vary.
