I'm not sure why you need 3/4 or 1 hp garbage disposals, (are you grinding tree limbs?).  We went with MOEN since the other brand offered by the hardware store was the same brand that I was replacing after 2 years.  I'd have given it 5 stars, but the pre-wired cord was 3" too short and I had to create a 12" extension cord so I could secure the ends.
