The comparison between the Outback and the Accord wasn't under optimal conditions because we did it in a partially snow-covered parking lot with a relatively short distance to accelerate and brake, but in both cars the ABS definitely activated. My son and I took turns driving both cars, so I had the opportunity to observe both inside and outside the vehicle. When I was watching the locking and unlocking of the wheels from outside the car I can't swear that the speeds were identical, but they were both in the 15-20 mph range.
 
The Honda system definitely sounds different as there is a distinct hum or buzz when the system activates that is reduced or absent in the Outback. In the Outback (at least in mine) it feels like the brake is being applied and released at a lower frequency with a harsher, more mechanical feel. This is consistent with my observation from outside the car, but I can't really quantify the difference. They may both be proper activation of slightly different systems. All I know is that after 10 years of driving Hondas, the feel of the Subaru system is different enough that I wish I could get confirmation that it is performing as designed.
 
I did the comparative testing while on a trip in Colorado (the Outback performed admirably in the mountains). Now that I am out of snow country, getting reliable road conditions to test the ABS may be difficult. This is why I am asking for other people's experience to see if there is a good reason to push the issue with the service department.
 
Thanks for your input.

The way you describe your ABS performance sounds exactly the way all 5 of our Foresters have acted. It is definitely different than the way my Tundra does it.
 
I think what you have is normal and as Elliot said it is just the different implementation of the manufacturers. I also have to say that the first time it happened on my first Forester it made me sit up and wonder if it was normal because of the feel and noise, but since all 5 have performed the exact same way I don't think about it anymore.

A very big factor that affects ABS is tires. Obviously less traction will force the ABS to work harder.
 
From what I read, the previous generation Impreza with the OEM tires produced horrific ABS response. After a change in tires, it was night and day.
