Seals rarely fail, this is not a realistic problem. The water level during wash is mostly lower than the seal, only during rinse cycles does it reach above the seal. If the machine fails for some reason during a cycle it can be drained through a drain hose which uses nothing more than gravity.

Front loaders use less water and with that less energy (which mostly goes into heating water), are less likely to tear clothes, have higher spin cycle speeds (1400 to 1600 rpm vs. 600-800 for top loaders) and can be (and often are) stacked.

Why would anyone want a top loader? What is the advantage other than the supposedly greater ease of loading which is negated by putting the front loader on a pedestal? I see no advantages, only disadvantages. It is not as if we never had the choice between these types as I remember them from the laundromat some 55 years ago. They were phased out, most likely for the reasons stated above.
