From my experience we always switched before Covid. After Covid they stopped and did the honor system, but now on our most recent cruises they have started switching again. That could just be coincidence though.
Personally I prefer the honor system as I'm usually scribbling fast and my writing is not very legible.
On a funny note, we recently switched with a couple who knew they were not doing well. They started filling in nonsense answers that just had us cracking up. Some were so good I gave them bonus points (I knew they weren't going to win so it was more for fun I did that...it didn't affect anyone else). It gave us a good laugh.
