Turnips are generally better than carrots, and onions are better than turnips. I use plenty of turnips for black soup personally.

As far as finding them, I just got lucky in a swamp biome, but in hindsight they don't seem very common and I haven't seen a lot of them in the 3-4 swamps I've found so far.
