An often overlooked factor about the fact that 29ers roll over obstacles well, is that they don’t generate as much force when you are working the backside of a roller.* I agree with you about geo, but if the geo is good on both bikes, the smaller-wheeled bike will be lighter and more manoeuvrable. It will also turn in more responsively and you’ll be able to tip it over further.
As with most things, there are trade offs involved when wheel size goes up.
