I have buddies with both. I have peddled both and my preference for FISHING in the Outback...its huge....very roomy, easy to stand and walk around in and very well suited for fishing. The Revo is faster, but also narrower....its better suited for longer trips and/or paddling. If you feel you will ever want to paddle then go with the Revo...the outback dont paddle well due to its bulk and fishability.
Either way they are nice boath......let us know what you do and go test both of em before purchase.
