Well we have returned from our QF7/8 adventures. New config both legs.
QF7 we had 44DEFG. Recline was fine however not sure if it is slightly less than standard? Nice and dark due to light positions. No real noise from toilet (flushing or PAX). Leg room in D/G is terrible due seat design combined with AV system and bulkhead seat. Would be awkward if travelling alone and not being able to share E/F leg space. No foot net (which I was disappointed with, I have read of peoples complaints, however I used to like them when they were around years ago, or on CX I think it was more recently). Generally great seats for a family.
QF8 we had 44DEFG & 44HJK for the 4 of us (glad the U/G didn't come through in the end, saved 280k points!). The toilet light on the starboard side would not dim when the door was opened (happened on both flights, however QFsource seems to indicate different aircraft so not sure if it is a common ailment). This meant that sitting in HJK, whenever PAX entered/left the WC, then the light levels increased dramatically, which did get a little annoying in the middle of the night. Did not happen on the port side or any of the other WC's (where the light only comes on once the door is locked). PAX noise however was not an issue. The ambient night time light levels in HJK were also noticeably higher than DEFG due to the positioning of the seatbelt signs.
Looking at row 43 there didn't seem to be a lot of legroom, however this may have been deceiving given the previous post.
Happy to answer any other Q's.
