Often discussed topic. Bottom line, it's personal preference. Some highlights I've read over the years
Below the ridgeline:
-More support for the tarp from wet snow etc.
-A place to hang wet gear
-A little more side to side strength
Above the tarp:
-No abrasion of the tarp against the ridgeline
-Allows the catenary curves of some tarps like the Warbonnet tarps
-Less chance of water ending up on your hammock since there is no line for water to flow along and drip on you.
For every pro or con there will be a way around it so as I said it boils down to what works for you.
Don't let life get in the way of living.
