I recently got 235/40/18 blizzaks on my Xi. Only had one snow storm since then and they're great,especially at braking distance.
We had a lot of ice after the storm and it's not a "holy shit, I'm going to die" feeling you get with all seasons.
Turning from a red light is still kinda sketchy, but that's to be expected.
Actually aren't terrible when it's dry either.
Discount tire will throw you a deal if you talk to them. I got all 4 mounted and balanced with the warranty for $750ish
