Terminator 3 or Terminator Salvation?

[Jezza]

We all know the first two are the best in the series, and probably always will be, but which is the best out of the two weaker sequels?

I personally prefer T3, because it feels more like a Terminator film than Salvation does and is much more enjoyable to watch. It also has Arnie in it, which makes it all worthwhile too, even if he did just about get away with it in the role, at that age.

But which do you think is the best?
