Pubnub and Pusher are nearly tied on overall homepage messaging — 75 vs 75. The difference comes down to where each invests its messaging effort.

Pubnub is clearer about what it does (84 vs 52 on clarity). Pubnub's hero ("Deliver the live interactivity your users want") names something concrete, while Pusher's ("Powering realtime experiences for mobile and web") stays abstract.

Pubnub uses a "Platform / Ecosystem" positioning while Pusher goes with "Simplifier / Easy Button" — fundamentally different approaches to winning the same buyer.
