A few years ago I was appointed AR at a youth cup final. It was a national tournament with the final at a Scottish league ground so a big deal for the teams and officials. I ended up on the opposite side from the main stand and technical areas. There was a decent crowd, several thousand, but they were all in the main stand and the side I was at was deserted. The strange thing was that there was hardly any action at my side for the entire match which went to extra time. Apart from half a dozen obvious throw ins I hardly had anything to do but it was a bright sunny day and I did pick up a bit of tan. On that experience I'd definitely say AR is easier.
