Iberia Airlines Iberia Plus - How is the bulkhead on the IB A340-300?

I will be on a USA-bound A340 from MAD tomorrow. It seems that the bulkhead 8J is available.

Is this a good seat? If I want to work on my computer, am I better off here or in an aisle seat farther back?

Thanks for any quick responses.

Can't really go wrong with a bulkhead - only issue is slightly restricted legroom as no under seat storage in front of you. However always remember that no one will be reclining into your space, which has to be a ++.
