I bought this and Revolution Unlimited at the same time so I can compare them side by side. Ergonomics and components are exactly the same except for the interchangeable thumb sticks. The software is the same and offers the same setup for both. I decided to keep this one because I play on a monitor that is next to my console. I can never get further from the console than the cable can reach. I also don't have to worry about running out of battery power during or before a gaming session. Therefore, from my observation, there are three additions to Unlimited: interchangeable thumbsticks, wireless connection, rubberized grip. If you need WiFi, of course there is no way around it. But if you're sitting close enough to have a wired connection, Unlimited doesn't offer any superior internals, software, or ergonomics.
