two totally different vehicles... So you cant really compare them.
For tons of open grass I would go with a bigger vehicle 1/8th 4WD, savage x, savage xl, LST2...
I also have a very long driveway about 1.5 cars wide and 800 - 900 ft long. So its kind of like I could go on/off road. The grass is pretty short and in some spots its just dirt or moss - I am also trying to stay around 250 - 350
