I like 550 Hz.  Some people feel that the ear is more selective at lower 
frequencies; the argument is that a difference of 50 Hz in pitch is 10% 
of 500 Hz but only 6.25% of 800 Hz.  It's an interesting 
neuro-psychological question that I'm not qualified to speculate about!

As you say it's a personal preference, and it's easy to change.
