Obviously the majority will side with the speedy because this is the lv forum. If you get the speedy, you could tide yourself over with their pond wristlet, which is 98 + tax. Best of both worlds? I think they are two very different bags, so it depends on your personal style. I'm craving one in the new brown leather though, and the mini pochette in azur, so again is all about what you like best! I never carried the azur speedy, but I know the satchel is pretty heavy.
I tried the Legacy satchel another day and it was very heavy. If you want a handheld bag, the Azur speedy will be better choice.
