I find that the spiral reamer cuts the wood away and the straight reamer scrapes it away. I find the spiral reamer works best to dress the hole after it has been sized. This is done by turning the reamer backward. It then burnishes the hole and makes for smother peg operation.
When you get right down to it, it is all a mater of preference and what you get comfortable with.
