I have driven both. They are both very capable cars. The SG is really really good with minor adjustments out of the box. Personally I have driven and/or raced most of the cars out there and I can tell you that the OD turns better than any 1/8th hands down. So much in stock form actually that we have been dialing some out of the car. Pretty rare for 1/8th buggies. The other great thing about OD is the car is super durable and parts are pretty inexpensive compared to most other cars. The serpent felt pretty good never really did anything funny. Jumps turns and overall handles pretty well. I'm sure you will like either car. One thing to keep in mind is that OD has awesome customer support wether it be from Hobbico one of the team drivers or Steve himself
