In my case it is the other way around.

When using WP-Cache we got problems with Internet Explorer when redirecting 
with Javascripts after manipulating cookies. The old cache was given to IE 

That's not the case with Varnish.

We have a lot of javascripts and feeds generated with PHP  that lives happy 
lifes because of Varnish.

For the record, we use memcache and xcache too.
