Haha I don't think there is right or wrong in terms of your preference. There is right or wrong in how you do the calibration though, such as how you place and position your mic, setting up for the better gain structure etc.
On the objective side, some of us are keen on using the U-mik mic and the free REW software to plot graphs to compare the before and after frequency response, impulse response, waterfalls plots etc. If you haven't tried that, may be you should, as I think you will enjoy the fun in doing it, if nothing else.
It is only through the use of the mic and REW, that I learnt I need to play with the crossover point after running Audyssey, in order to at least get the L/R towers to play nice with the two SVS subs because my ears/brains really couldn't tell if they played nice or not, but evidently the mic has much better luck. By the way, I was amazed to see that cheap looking Audyssey mic producing very consistent results, despite its supposedly very mediocre error margin.
