What is the difference between using this:
(string)value; // typical cast

and this
Convert.ToString(value);

Is one preferred over the other? Why?

it depends on the context.
usually, casting is only used when you KNOW that the variable (value) is of type string under the hood (for example a string assigned to the generic object data type).
convert is used when the variable is not of type string.
there is a third thing, most objects have a .ToString method, which is, in case of strings, the preferred method.

for other data types, like numerical/dates etc, only your 2 methods are possible, but again, it depends on the context
