I used to have the WP-Super-Cache plugin on my site before I switched to W3-Total-Cache.
Although both are good, W3-Total-Cache scores by being more comprehensive and feature-packed than the competition. Of course, this also means that it is more complicated to configure than the others.
There are also a few bugs that exist (auto minify sometimes messes up .js files, "verify page rules" gives false positives, etc.), although few of them are likely to be fixed in the next update.
All in all, this is a great plugin and would love to see the few remaining issues fixed. But the last version came out over a year back and am desperate to know when the next version is coming out!
