If the line is really long, then using the machines is worth it. (I joined because I had had enough of the 90-minute crazy lines which you see in MEX if you land at the wrong time.) The machines are clunky, you have to type in a lot of info, and usually at least one of the three at MEX T2 isn't working. In fact, the first time I tried to use a machine after joining, they were all broken. Luckily in that case, an Immigration agent let me come to the front and go right through instead of wait in the epic 90-minute line.
