I'd say you're comparing apples to oranges. The determining factor for most is the depth of your pockets. If you want the finer things in life and have the money to pay for them, then by all means go with a big 45ft diesel pusher. If you tend to be more frugal (meaning you avoid waste) then a gas MH should be your choice.
My 16 year old gas powered Trek has a china toilet, Corian counter tops and full body paint and I'm tickled with it. Unless I find a way to swap it for a better model floorplan in another Trek, it will be the last MH I'll ever have.
Happy travels whatever your decision.
