No, they are basically identical.
neither of them will have fabulous life expectancy.

There are some secondary considerations:
spindle length should match what your crankset is designed for, as this helps determine the "chainline" offset ( https://www.sheldonbrown.com/chainline.html ), the drivetrain's offset from the centerline of the wheels. The difference between the two you list will probably not be noticeable.
The threaded "cups" are what attach the BB to the frame. The steel are a bit heavier and rust more easily. The alloy are lighter and usually found on the somewhat better models, so their presence may indicate better quality or materials in other parts of the BB as well. Whichever you choose, when you install it's very important to properly lubricate the threads with a good grease (or even anti-seize compound if the cup metal is different from the frame metal - i.e. alloy vs steel).
A BB takes a lot of punishment, yet square taper ones are quite cheap. Often you can get substantial quality, material and longevity improvements by moving up from a $10 BB to a $20 BB, but you need to research the manufacturer and construction details and talk to someone with experience.
