I heard that many people had issues with W3 Total Cache on a WordPress MultiSite install. And then I see this on the plugin page:
Compatible up to: 3.2.1

Seeing that I’m running on WordPress MultiSite Version 3.4.1 and that it’s been over a year since the last plugin update, I’m really wondering if this plugin is a good choice for me.
Or should I use WP Super Cache with WP Minify instead?
W3 Total Cache is a GREAT option! One thing to keep in mind is that you need to individually work with each site for the settings – there is not a global settings area (yet). The next version is said to have this built-in. If you need this “right now”, then WP Super cache does this and is a great option, if you can hold out for a little bit, then W3 Total Cache would be my personal recommendation. Thanks!
In short yes … I’m using it on my own multisite with about 7 subsites and its working fine.
If you have many users, then this probably a good choice as it can be activated per blog.
It also has a great deal of integration for CDN, minify and and control over the caching headers.
We use it with great success with about 2 million page views of traffic monthly and it relieves a great deal of stress from our servers. As others have mentioned, its configurability is also a plus allowing you to control which sites use it or not.
Our experience is using IIS so your mileage may vary if you’re using Apache or ngix
