If you do a little searching you will find that almost every truck worth buying has be compared to each other in more than one thread......Especially the Savage and the Revo.
Here is my two cents.....gangsta is way on track with it. The Revo is a little quicker more nimble...more of a racer....the Savage will take head on crashes all day and laugh if off where a Revo would crush an engine mount. BTW is why I went to Savage from a Revo and have never looked back. I realized I don't have the mad skilz so I needed something damn tough and so far both my Savage 25 and XSS have held up. And I love big blocks.....easier to tune and just go out and have fun with. However put the 3 speed in a Savage and it will keep up with a Revo speed wise......until you put it in a place that needs some real torque....then the 2.5 Revo just gives up and goes home. So what do you want it for racing or sick ass bashing?
