Recently did LHR - JNB and back in 25D. I much preferred 29C on the 773.

There's a lot of passing traffic in 25D using the forward toilet on the port side. There didn't seem to be a forward toilet on the starboard side (that was for Club passengers), so it increased the footfall along the C/D aisle.

There is a seat back pocket on the rear of 23D but as 25D is over an emergency hatch then everything must be stowed above for take off and landing. The TV monitor is also folded away at this time.
