Tom, If it was my choice I would go with the Panny, then again I'm a big fan of plasma. Depending on your seating distance I don't think you would gain anything from 1080p over 720p.
I like the ability if so desired to have the flexabilty to mount the screen on the wall, I also think IMO that the plasma has the best overall picture for any type of room lighting. I envy your choices, I have been trying to figure out how to get myself a larger than 42" plasma without foul play or an earthquake knocking over my current set
