I think people tend to lose sight of the fact that you 'travel' for a long way at any big airport. At Doha (transits), you walk off the plane onto a bus which takes you to the transit terminal, where you are bussed to the bottom of the steps of the next flight. Arrivals are even simpler.
Any other big airport and you tend to walk (or travelate) for ages, sometimes involving train rides.
I find Doha pretty good. Especially as the airline is really good.
