A \Centerstack is a "long stack" using a fixed baselineskip, defaulting to \normalbaselineskip. You could increase that baselineskip, as in the 2nd example. However, there, the added baselineskip applies to the top and bottom rows, as well, which is probably not desired.
In the 3rd example, a "short stack" is employed, which uses a constant gap between the content of each row. However, short stacks are not vertically centered, so you have to apply a \vcenter to achieve that effect, if desired.
