To get the shortcut, you need to press the modifier key first, and
assuming your two keys are close enough to use with two fingers of the
same hand, I don't think it makes a great deal of difference.

Ctrl+_ shortcuts where the letter isn't within reach of my left hand
(I'm right-handed), are slower / harder than many two letter
combinations.

Its not a great shortcut to have to use Shift + letter, then another
leter.

Assuming no modifiers, a two character shortcut has the same number of
operations as Ctrl+_, just has a different ordering of keypress /
key-releases.

I don't think it's going to be the press / release time which dominates
anyway.. its more about what keys are near your fingers.
