Craviotto and N&C are equally good.
You wont hear a big difference in the sound.
Brady have a different sound, especially as they use local woods such as Jarrah.
They are all good choices.
I would advise that a maple drum will be more flexible and versatile than a Jarrah (or similar native wood).
It depends on the sound you are after and your budget.
I would suggest trying a Brady and a Craviotto and take it from there.
Again, all three companies make very good snare drums.

I've been playing a 6x14 DW snare with maple Craviotto shell for the last several years that I found on ebay.  It took me a little time to dial it in (snare drums often give me fits), but it rapidly became my goto snare drum.  I play rock, country, and big band and small group jazz, and it has never let me down.  The drum is crisp and sensitive at low volumes, and rim shots will cut right through loud guitar amps or large horn sections.  I did replace the DW drop down strainer with a Trick, and put Puresound snares on the bottom.

I have no experience with the N&C or Brady snares, but would not hesitate to buy another Craviotto, and feel no need to add to my meager collection.

I purchased a Craviotto 5.5x14 birdseye maple snare when he first started making them. Matter of fact it's #33 of the run. I was so happy with the sound I went back and bought a 6x14 Cherry snare to go with a Mapex Cherry set I have. I have a number of snares to pick from, but those two are both "go to" snare drums. Nice woody sound with an "awesome" factor. 

Last few Cravs I've seen (mine included) use the Trick throw, and I've seen a couple Unlimiteds with the Dunnett R -- haven't seen any with Nickel lately, so fortunately that may be a non-issue.

That being said: Add another vote to the Craviotto pile -- they are great. However, I haven't heard the N&C you mention.

All my Crav's now have the Trick. Dan mentioned a second hand drum from 2004, which is why I brought up the Nickel issue.

Is the 2004 Craviotto more expensive than the Brady?
Is the Brady also used?

All things being equal, I would honestly go for the Craviotto, unless you came across a used N&C to try too.

I have 4 x Craviotto snares, probably 2 too many. But I do make a living from my drum sounds..............

Cool.  Great snare drums.

I think you did the right thing, especially as the Brady was more expensive.
As an Aussie, maybe a Brady is in your sights down the track.

I do endorse N&C (sort of loosely).

I put 42 strand Puresound wires on my maple Craviotto. When I nail rimshots people stop dancing and just look. 

Smart move Lou!  A snare drum like that is the perfect vehicle for expression.  You deserve it and the places it will be able to take you.

You live in/near Amsterdam?  OMG- I want to retire there... seriously!
