[Hummingbird] W3 Total Cache conflicts with Hummingbird?

Hi there,
Our website https://onlydinosaurs.com/ is now working with MaxCDN and Hummingbird.

1. We noticed that there are over 40 css resources. To reduce, MaxCDN team recommend W3 Total Cache plugin, which has multiple functionalities for caching/optimizing. In your opinion, is this a good idea?

2. Last week, we installed WP super cache plugin. And it appeared conflict. How about W3TC? Will they conflict?
