In general, what are the advantages of using Grid versus a combination of Column and Row? Is Grid better in some situations but not others?

For example, is there any reason why one would do this:

Grid[{{"Some text I want above a formula:"},
      {Integrate[f[x], x]}}]

versus this:

Column[{Row[{"Some text I want above a formula:"}], 
        Row[{Integrate[f[x], x]}]}]

    $\begingroup$ It seems Grid is natural way of dealing with arrays while it is more convinient to use Rows for rows with different quantity of columns. Of course with SpanFrom~ and others You can do whatever You need in the way You want to. I don't see any limitations favouring any of this ways. Do what is shorter and more convinient. $\endgroup$ – Kuba Feb 13 '13 at 20:06

There are several differences in behaviour. One is that Row will be line-wrapped if it does not fit the notebook window:

Grid will not.

Also with Grid the alignment is global, so the $n^\textrm{th}$ elements in each row will always line up vertically with each other. This is not the case with several Rows in one Column.

table = Table[RandomInteger[13, 10], {5}]

Mathematica graphics

Grid allows merging several grid cells too (see e.g. SpanFromLeft). This is just some of the most obvious differences.

    $\begingroup$ Grid also allows you to algorithmically specify things like background coloring (although you need a degree in math & magic to get your specs right). $\endgroup$ – Sjoerd C. de Vries Feb 13 '13 at 21:33

If I am making something ad hoc I often use Column and Row but later re-write as Grid once I have settled on what I want. I find Grid easier to maintain and more flexible.

Grid and Column are both GridBox whereas Row is RowBox. There are some limitations with RowBox -- for example one thing that comes to mind is limited FrameStyle compared to what is available in GridBox

Row[{1, 22, 333}, Background -> Red, Frame -> True, 
 FrameStyle -> Directive[Dashed]]

Grid[{{1, 22, 333}}, Background -> Red, Frame -> True, 
 FrameStyle -> Directive[Dashed]]

enter image description here

For some reason I always seem to find it easier to position elements in a Grid cell than a Row -- maybe just lack of perseverance on my part (?). Row allows numbered alignments Alignment->{-0.5,0.5} but I don't really see the point. On the other hand this would be useful in Grid but a known bug since at least V7 prevents it from working.
