Straw poll: poster or talk?

At the moment this post appears, I’ll be standing in a poster booth desperately hoping that at least some petroleum geologists have (a) stuck it out to the bitter end of the conference, and (b) can feign an interest in Archean paleomagnetism. In the meantime, I’d like to hear your thoughts on the following question:

If you were given the choice, would you prefer your conference presentation to be a poster or a talk?

I’d be interested to hear the reasons for your answer, and what level of the academic ladder (post-grad, post-doc, junior/senior faculty) you’re currently at.
