I've not flown F on the A380 but for the others I'd put them 789,747,777-200,777-300.

The 789 is really great, especially if you're on your own. With the exception of the single loo at the front there really aren't many down sides. It's not too quiet that you end up hearing chatter/eating etc. I like the big screen, the image quality is a real improvement on other aircraft. Having the moving map details on the handset is quite nice to have as well.
The 747 is very good, especially the newly refurbished aircraft with the Panasonic IFE. I personally favour row 2 to row 1 though.
As for the 777s, I quite like the -200, however will actively avoid the -300. The inability to easily navigate between the two toilets at the back of the cabin is a real gripe I have.
I'd like to try the A380, but following my experience in Club on one I'm not in any rush. It was too quiet - all I could hear on a night flight was people talking. And I had a row to myself so they weren't that close.
