I've toured on both, and also on New Zealand's North Island which is worth a visit in it's own right. I didn't have any problems at all with the logging trucks in Tasmania, but that may only be because I come from Queensland and am already used to anything a bad driver can throw at me. In fact, the worst drivers I saw in Tasmania all had Queensland registration, go figure.
From my experience, it comes down to a question of how much you like cold weather. I found the South Island a lot colder than Tasmania, or indeed, anywhere else I've ever been (including Scotland). The weather in March may be more amenable to cycling in Tasmania, but if you're already visiting the South Island beforehand, you can make that judgement when you're there.
Whichever you choose, just make sure you set aside time to ride the other one at some point in the future. You won't regret it.
