I know a guy who did extensive research and bought a Speed Queen washer and dryer, simply because most of their business is in commercial units. They're built simply and made to last, but not easy to find at retail.
They will be much louder and may be less energy efficient.
Any reason to expect them to last longer?
They're built for commercial/industrial service.
They are more serviceable at least, you can get the replacement parts pretty easily along with manuals. They're purposely made that way for hotels/laundromats/etc where you can't just swap it out.
