Well Tyrael didn't have a good option for the Black Soulstone. Since it's a man-made construct, he didn't know if he could destroy it, so he opted to hide it somewhere far away from both angels and demons.
Unfortunately, it didn't stay hidden for long.
Why is it that Tyrael didn't think of destroying the Black Soulstone on the Hell Forge?
I'm sure he considered a lot of options, but the thing is, because the Black Soulstone is different than the soulstones of the past (like Mephisto's), and because it's a man-made construct, Tyrael wasn't sure what would happen if he tried to destroy it. Who knows what might happen if he attempted to do so? No one knows and such an attempt could prove to be catastrophic.
Therefore, he felt that the best and safest course of action was to keep the Great Evils locked within the Black Soulstone, and then hide it away from the influence of both angels and demons.
Now there are other dimensions that angels and demons created with the Worldstone, certainly. They're not really the sorts of places you'd want to go on vacation, though. Most of them are rather sad, empty places, and they are still the realms of the angelic or demonic faction that created that particular dimension.
The only truly neutral dimensions are Sanctuary and Pandemonium, but Pandemonium still has demons and angels in it, and Tyrael's mortal allies (the new Horadrim) wouldn't have been able to help him hide or guard the Black Soulstone in Pandemonium. As such, Tyrael believed that hiding it on Sanctuary was the best course of action out of the limited options available to him.
