The difference in performance seems to be below 10% (at least on
www.phpbench.com)and nobody can guarantee that this will be the same
with future php releases. There may be optimizations rendering current
results completely useless.

Adittinonally using different php caches may result in very different
benchmark results.

Readability is also an issue as David already pointed out.

 Marc
