My '07 STi doesn't have traction control outside of the usual Subaru AWD, and I don't mess with even that. In more than 3" of snow, my bumper cover and splitter act like a stupidly expensive snow plow for only a half a block, so I don't drive in those conditions. In short, if you do drive in those conditions, then your question proves that you're more experienced than I am
OTOH, in the sideways rain that is typical of Puget Sound between October and May, leaving everything else even and trusting to my Hella TPS has been very reassuring. No gettin' sideways without wanting to, no loss of grip in corners, or spinning wheels at crosswalks. Bear in mind that I'm running 18x9's with only 375atq. Your experiences will vary depending on torque and contact patch profile.
But full disclosure: In my '08 WRX, I left TCS on in all weather, mostly because my Pacific Raceways instructor told me to leave it alone. He figured that whatever I could do in bad weather with TCS on, I might be able to do better with it off, but that the odds were that TCS was better rather than worse, so best to get used to it on before trying out any slick corners with it off. Was he being too cautious? Perhaps. Then again, as he often told me, it all really came down to a balance between foolhardiness and insurance premiums.
(I chickened out and bought an STi rather than risk my purdy WRX on winter streets)
I don't recommend that you mess with it, but if you do, them please PM me and let me now how that goes
