What's your favourite gear ratio?

Going for a 55/42, 11-23 combo with 53/39 chainrings as extras for my first geared bike in more than 10 years.

I changed to fixed last year, after 25+ years of road cycling, but still posses a geared bike. The fixed is ridden in preference, reserving the geared bike for very long rides.

Now, I can't imagine a day when I'd prefer geared.
