Off the shelf rear axle assembly: Dana 60 instead of 8 3/4"? Pros/cons?

While it may be overkill for naturally aspirated small block people, it looks like it's much easier to find Dana 60 units these days, particularly from major vendors who sell complete assemblies and the cost difference is minimal.

What pros and cons should be considered?

How much heavier is the Dana?
Would it require heavier duty shocks/springs?
Does the extra unsprung mass notably impact handling?
How much more/less power does it require to turn?
Is the increased effort to swap ratios that big of a deal?

Thoughts are very welcome here.
