Which one is better? I want to make one of these for my brother's birthday.

I know they both have high ratings. Compare and contrast them for me please!

I've made the Darn Good but not the Amazing. I've also made the Epicurious Double Chocolate cake, the Hershey's Perfectly Chocolate, and others I can't recall. Still the best one (for my personal tastes, which is: the chocolatier the better) is the Scott Clark Woolley Fudge Brownie Cake. Recipe is here on p3 of the Hershey's thread http://www.cakecentral.com/cake-decorating-ftopic-52587-30.html. Of course everyone has their own personal preference, but no matter how many new "fantastic" recipes I've tried, it always comes back to this one.

Also here is a great thread comparing a selection of scratch-baked chocolate cakes. http://www.cakecentral.com/modules.php?name=Forums&file=viewtopic&t=639593&postdays=0&postorder=asc&highlight=scratchoff&&start=0

I prefer the Amazing over the Darn Good. I could not get the Darn Good cooked in the center without burning the rest, and I cooked at low temp with bake even strips.

Just my experience.

Well I just put two layers of the Amazing in the oven. We'll see

Both very good!

Neither. THIS chocolate cake: http://www.epicurious.com/recipes/food/views/Double-Chocolate-Layer-Cake-101275
