There is simply no substitute for prototyping. If you want to know if a drive can climb, defend, push, turn or move sideways effectively, the only way is to make one and put it to your own test. By now many teams have done just that and have played the game, even if only with students portraying robots. Most have come to the conclusion that some pushing will take place, some climbing over the bump will be needed and accurate movement and position of the robot for kicking is a must if you want to score. If you prototype you will know if your robot will slide sideways off the bump, if it can be pushed easily or if the drive system will work at all.
I will answer again as I have so many times before. We do not decide on a drive type until we brainstorm, prototype and test. Now one should.
