The short answer

InSinkErator Badger 5 1/2 HP comes out ahead by a narrow margin (4.4 vs 4.3). The gap is mostly about Apartments, rental units, vacation homes, and small kitchens with only occasional cooking, where reliability and the lowest installed cost outweigh noise and grind-quality concerns. — read the strengths below before deciding.

2 sources1 derived

No disposer is installed more often in North America than the Badger 5, the default 1/2 HP swap-out unit for two decades. Reviewers (shouldit.com 5.3/10, This Old House 4.6/5) agree on the same three things: reliable, easy to install, noisy. Buy it for small kitchens, apartments and rentals; skip it for daily heavy cooking or noise-sensitive layouts.

Strengths
  • — Most widely installed 1/2 HP disposer in North America, with parts and service technicians available anywhere
  • — Compact 11-1/2 inch height fits the tightest under-sink cabinets
  • — Lift & Latch 3-bolt mount means most homeowners install it themselves in under an hour, especially as a swap-out for an older Badger
Watch-outs
  • — Single-stage grinder; struggles on fibrous waste, fish bones, and raw chicken in bench tests
  • — No SoundSeal insulation, so noticeably louder than any Evolution-series unit
  • — Only a 5-year warranty (half the warranty of mid-range Waste King units at similar street price)

InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed
Ranked #5 in Best Garbage Disposals
InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed
3 sourcesall derived

Batch-feed safety is the whole point of Cover Control Plus: the disposer only runs when the magnetic cover is locked in place. InSinkErator pairs that mechanism with the full Evolution-series 3/4 HP MultiGrind chamber and SoundSeal insulation, which makes it the quietest premium batch-feed unit reviewers found. Homes with small children will find the upcharge worth it.

Strengths
  • — Magnetic CoverStart batch-feed activation means the unit cannot run without the cover locked in place, eliminating accidental starts from dropped utensils or curious hands
  • — 3/4 HP Dura-Drive induction motor with 2-stage MultiGrind handles dense and fibrous scraps refined enough for hassle-free drain flow
  • — Full SoundSeal Technology insulation, anti-vibration mount, and Quiet Collar baffle keep operation conversational
Watch-outs
  • — Batch loading is slower than continuous-feed for big cleanup sessions
  • — Cover requires precise alignment to engage the magnetic switch; some owners report cover-stuck issues that need cleaning
  • — Premium price for a 3/4 HP unit, driven mostly by the safety mechanism rather than grinding performance

How they stack up

InSinkErator Badger 5 1/2 HP

Roughly half the motor of the Evolution Compact 3/4 HP and a third of the Excel 1 HP, with single-stage grinding instead of MultiGrind. Lacks the bio-charge mechanism of the Septic Assist and the safety mechanism of the Cover Control Plus. The Badger's only structural advantage against any of those is its shorter cabinet footprint and roughly half their sticker price.

InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed

Shares motor and chamber design with the Evolution Compact 3/4 HP, but trades continuous-feed for cover-locked batch operation and adds about 5 oz of chamber capacity. Roughly $50 more than the Compact for the magnetic safety mechanism. Quieter and finer-grinding than the Badger 5 1/2 HP but at more than twice the price; the safety mechanism is the buying reason here, not the motor specs.
