I was pretty firm before about sticking it with Spb backup (as oppose to Sprite)just because it's cheaper, and pretty much do the same thing.
But, after obtaining the new version, and trying it out couple of times. I think the extra $10 or so for that Sprite is charging is very well worth the money.
Sprite has more options, and more control, and it seems for polish than Spb. Of course in the end, whatever backup program that can restore my device without any problem is the winner. So far, both program does it without problem, and so it's just fair to keep both of them on my device.
So if you're shying away from Sprite because it's $10.00 more, don't. The extra $$ is well worth it.
