I've had both, and in the open plan I find I have my headphones in so much that I might as well be working on my own private island. I'd rather have my own quiet office than blare music all the time, but both work well enough at driving out distraction.

Neither of these jobs have been team oriented though, I am 'the rails guy' at both, so isn't much knowledge transfer except from stuffy stakeholders in formal meetings either way. I'm sure it's different in a team environment.
