I'm given to believe that they're very similar things as well. How similar will need to be discussed and debated further, with careful comparisons of features and uses.
As for the analogies of wands and IDs?
Hmmm... Really, I think it's more like the difference between having a shop full of old hand tools... and having a shop with a CNC machine.
It even fits in that well made hand tools can do wonderful things, but require great skill and finesse to do so. CNC Machines, on the other hand, require less physical skill, but much more mathematical knowledge. At least, for the part where you're making your own spells. (Which is why Nanoha was so damn impressive in her youth. She was not only a pint-sized power house, but also had the mathematical capabilities to go from being a total novice to creating Starlight Breaker in about two or three weeks!)
