The Kitchen Aids with the bowl that lifts is the better unit. Has a much more robust gearbox. BTW, that gearbox should be cleaned and repacked with grease every 5 years or so.The manual makes no mention of this but that maintenance will make it last indefinitely. The grease does dry out and if that happens the gearbox will go to ****. Plenty of Youtube vids on how to. My wife's is 30+ years old and still working like new.
