Well,

My guess (no facts here) would be the first is slower.

First the "'s need to be checked for $variables, it would be quicker to put 
'.
And then an operation of copying needs to be done. Allocation as well on the 
c side
for the new, larger variable.

Then the display.

The second snippet displays the lines without the additional operation of 
allocation/concatenation.

Who knows though..I'd like a more fact based explanation.
