I like both kind of games. I love my BSD if I just want to play some shorter and simpler rounds of pinball. If I got time and want to go deep I play my JP2.
But I agree. for home use I prefer games with deeper rulesets. If they have simpler ones they have to be very good. On the other hand I like to play shallower games with friends that are harder. I don't want to have them stand around 40 mins and watch me play before they play their 1min ball.
