Hey Vinny,
Hulu Plus is required for streaming devices such as the Roku players, Apple TV, Playstations, etc. The content is more or less the same with a few key differences and limitations for the non-plus version that you can find on their website.
To be clear, though- you DO NOT get Hulu Plus when you buy a Roku, it just has an app that you put your subscription (around 8 dollars a month) info into and can then use the service through your device very similarly to how all of the Netflix apps work on these types of devices.
