I had my first trip in an A380 SYD-DFW and return in November. Travelling with two young children, I was favourably impressed by the aircraft, compared to my last long distance trip in a 747.
Admittedly the seat spacing is not really good enough, but you have to consider that in light of the fare paid. Noise level was quite satisfactory, and no real complaints about the flights.  The only complaints about the flights related to passenger handling on the ground, including barely making a connection in DFW, and missing one in Sydney, and luggage missed transferring - ground facilities, especially baggage handling, are not up to that number of passengers. 
In comparing 1953 and 2018, you need to take into account that in 1953 the only fares were first class - and even then were much more expensive than today when inflation adjusted. The large "cattle crates" are what has made flying practical for most travellers - in fact, what has made travel practical for most travellers. The speed of thee is limited by the physical properties of the atmosphere - travel any closer to, or over Mach 1 imposes what the market has judged to be unacceptable financial and environmental costs.
On the other hand, in 1953, air travel required that you turn up for an international flight perhaps half an hour before take-off - today, you need at least three hours.  On the ground is where things have gone backwards!
