WP Super Cache vs W3 Total Cache

I have recently wrote a guide for the WP Super Cache plugin. I use it on every site I make and love its functionality.

I was wondering, does anyone have experience with the both the WP Super Cache and W3 Total Cache plugins? I have heard that the Super Cache compresses files better or at least, has a better caching engine. I have not been able to find reliable info on this subject. So…

Can any long term Cache Plugin users shed some new light on this topic? I have seen old posts, but I think both plugins have been updated since then.

Thanks!
