Is the traditional cut clasp nail still best for chipboard flooring
sheets, or would a ring nail be better?

I use Posidrive screws in drilled and countersunk holes. The main reasons
for using nails are speed and cost. For the d-i-y-er the savings on either
over using screws is not likely to be significant and screws are easier to
take up during later d-i-y projects.
