During a recent Vegas trip I flew into and then out of McCarran Airport.
McCarran was a little less friendly than San Jose. Less places to eat, more slots, more gift shops, more people looking exhausted instead of perky and tech-conscious.
The TSA was a little more involved as well and I'm fairly sure I qualified for pre-screen and they simply didn't let me know which line to go into. The TSA was friendly, but it's still a little bit of a downer to be body searched and step into a large machine.
Parking was easy and though their elevator is quite difficult to figure out I had no baggage so for me the process was, while not as quick as San Jose, still fairly speedy.
I wouldn't mind flying back to and from McCarran, but it's definitely not as cush as SJ.
