About the only thing worse than ABS on ice is no ABS on ice:
FYI the long and short of this link is a Honda Fit driver from Alaska asking about disabling the ABS, then a discussion about getting the proper tires, then a confession that he compared his Fit with ABS to some other cars his family drives, no ABS, and they were even worse than the Fit was stopping on ice.
Every situation is different. In slippery conditions tires first, but if you have to choose between ABS and non-ABS you bought the wrong car to begin with. Subaru engineers sell cars equipped with ABS and VDC because they believe they are safer than selling cars without these features.
If you want more flexibility adjusting the various systems, get an STI or some other car.
