I dont know how may times, and on how many forums i have preached this, but buy BOTH greenstuff and brownstuff and mix them together! The perfect sculpting material!
GS + BS is ok, but as with everything it comes down to what you want to do with it. Use the right tool for the right job. GS is softer and more flexible, BS is brittle and is good for carving/filing down afterward. Mixing the two will get you somewhere in between. BS also cures faster.
For GS, try mixing 2:3 blue/yellow. It is a lot stickier but more malleable for general sculpting. 1:1 is good for “foundation” sculpting - building armatures or base layers like cloaks, armour, limbs, etc.
Also, totally incidentally, if you use a desk lamp to cure putty more quickly, BS will expand quite dramatically if left under too long. GS will also discolour if overexposed to heat, becoming a dark green.
Funny you should mention Gale Force 9. I actually have the GF9 Brown Stuff. I know where to get the GF9 Green Stuff too. Thanx for the suggestions!

Actually, like GW, Gale Force 9 repackages Kneadatite products. Generally you'll be able to find them in different places by looking for Kneadatite Blue/Yellow, Brown/Aluminum, Brown/Neutral, or Black/White.
As to which is better, it all depends on what you're working on.
Greenstuff (Blue/yellow) is generally very sticky when first mixed and is good for working on more organic shapes, it also has the longest work life of the Kneadatite products.
Brownstuff (Brown/Aluminum, or Brown/Neutral) is less sticky than greenstuff but holds edges much better, and cures harder. It's work life is shorter than Greenstuff's.
Add the two together (As Warplockmonkey suggested) and you get the best of both worlds.
I am asking if this is right. If you were going to make press in molds (using a block of putty and pressing something into it to make a mold) would you use brown stuff to make the mold and green stuff to reproduce the mold?
I guess it might help, with it curing harder, but its not necessary really. GS when uncured is very squishy and when cured can still be pretty hard - getting a clear impression won’t be difficult. The thing is getting the two bits of putty apart, so just make sure the “mold” is wet when you do it.
