Vacuum packed mussels - simmer or microwave?

[NoSoggyBottoms]

Bought some mussels which are vacuum packed. Instructions say I can simmer them in a pan or microwave them...both methods involve taking them out of the vacuum pack.

But which way do you think would give the best results?

Thanks

I've not tried microwaving. Simmer is pretty straightforward.

I'd be worried about over cooking in the microwave. Bullets of mussels are not pleasant!
