Well, I have both. The original
Vector from 8 yrs. back and recently aquired
Core B/O and I have to say that they are the same size physically, but
Core looks a tad smaller due to the black color.
As far as readability, my
Vector (positive) is perfect and
Core is so-so.
I can read
Vector time fine in dark without glasses, but for
Core I need glasses.
In bright sunlight (daylight) the readability on
Core is fine and excellent on
Vector.
If I had to decide on which is better and not letting the "new toy" factor of my
Core give it any edge, I would have to say that readability goes to
Vector, functions go to
Core as well as the visual effect, but I could not select between the two, these are so different. Maybe it would be easier to decide if my
Vector was negative.
