Interesting we are all different. I rarely use them for skiing due to speed and thus potential forces involved if it goes wrong but then I don't do deep powder when loops stop you losing them completely. I have had to let go of the poles many times over the years where if the loops were used injury may have followed. I've seen too many folk using loops and have problems like getting up after failing or with getting on off lift because they keep the loops on at all times.
I mostly do not use them walking, but do find them an advantage going up hills - it's an age thing! Will always remove loops when walking fast(er), on rocky terrain or going downhill so that I can let go if required.
Everyone to their own. I would always want them to be there to give me the choice though.
