Pros

Cast iron motor housing sheds heat, so it holds up to long run times in a wet spring
The float sits on the pump, so it fits a standard 11 in or wider pit without snagging the pit wall
Clears a typical basement lift: about 2,000 gallons an hour at 10 ft
Made by a long running US pump maker with parts and service through plumbing suppliers

Cons

Flow drops off quickly above 15 ft, so it is not for deep basements or long uphill runs
Costs more per gallon pumped than the plastic 1/3 HP pumps
Only a 3 year warranty, against 5 years on the Zoeller M63
