			I almost never buy giants, but I do use them if I find them.  Giants really aren't great, but they are both reasonably strong and quick.
Dwarves, I do buy.  They are incredibly useful for transporting stacks through hills, and are 20 strength when attacking in any terrain (not too shabby for a one-turn unit).  My dwarves do attack btw, stacks of dwarves destroying  much more valuable hero stacks on more than one occasion.  I don't buy dwarves very often though, they are just too expensive.  I prefer to save my money for more game changing units (the red dragon is just too cheap to resist).
Not sure if the dwarf is really a better unit than the giant, it is just a more specialized unit.  Great in a big clump of hills, and quite good to build near a port (where they can hop on board a boat to give their stubby little legs a rest).
