Left-to-Right in all circumstances, easier for me. Left-handed.

Right-to-left always leaves me hitting arrows in right-handed columns as a jump.


I think reason left-to-right works best for most people is because PR usage leans to left-to-right rolls for comfortable ascension of tone for build-up's & ramps before a drop. (think of ascending pitch before a dubstep / trap drop)

right-to-left is more commonly used in descending pitch involving bursts, or quick transitional bursts between measures, which can tend to be executed much faster than left-to-right. (Think piano descension in Tenimuhou)
