Suites is much better and much different experience from other First Class product while SQ 77W F is a glorified Business Class seat and nothing else.
I see what you mean by the partition extending out just far enough to be annoying.... I had in my mind it would be sort of the equivalent to LH first class... but looking at some personal photos from our last trip pre-CoVid, LH has no real separation between the seats if the divider is lowered. Anyone have any insight as to the viability of it being workable if in the SQ suite one px was seated in the recliner, the tray table open, and a second px were sitting on the bed (the bed platform being lowered into position)? Probably not so much for dining together (although that would be a bonus) but just so we could play cards or something to kill time on the 13 hr flight?
