I agree, I have a Whirlpool version and it’s still a tank. I think some of the criticism comes from the fact that the newer mixers use a plastic sacrificial gear, which is designed to fail before the motor. Other than that, they are virtually identical to the Hobart version (you can buy parts from KitchenAid/Whirlpool to repair/restore a Hobart mixer)
Good cast iron is the true BIFL… It’ll last your life, then your kid’s, then their kid’s, then theirs and so on… It needs to be seriously mistreated and neglected for a very long time until it becomes unusable
