Can you tell the more compressed version?

So I’ve been watching the various endings to Paranormal Activity (yes, I own the film – digital copy while on the go is a godsend).

While I don’t mind watching the film on DVD, I do like to watch movies while using my iPhone, and therefore the movies need to be seriously compressed.

I usually use VisualHub (now defunct, unfortunately), but sometimes dip into Compressor for the final encoding.

Today, I started to use Evom and I’m quite happy with the results.
While Evom did take much longer to re-compress my 1.6GB file (about 2 hours, compared to about 60-70 minutes with VisualHub), the resulting file size is a shocking 250MB less than what VisualHub gave me.

Here are the two compressed files, side-by-side. Can you tell which is VisualHub’s reduction and which is Evom’s?

Final note: if you CAN tell which is more compressed, do you really think it matters on the iPhone screen? I don’t.
