We flew this past summer with a bassinet outbound A346 and return A380. I did not see any difference in size, sturdyness or mounting.
We were on the window (2seater + Bassinet) on the 346 and in the middle section on the A380 with another family (4 seats, 2 bassinets).
No experience with SQ here.
edited to add that both flights were excellent with a great friendly crew. We'll do this again next summer.
