Strategy and expected return % are identical, but variance is different. I think most players with an advantage orientation will choose multi line games whenever available because of the lower variance for equal coin-in.

Some of the newer multi line games incorporate volatile bonus features that require additional coins per line, but I'm talking about generic multi line betting 5 coins per line.
