According to Nigel Calder (Cruising Handbook - pg. 473):

"When a carabiner-type (snap) hook twists around a pad eye it can trip
itself loose. Come type of locking hook is much safer."

He provides an photo to illustrate.

That being said, I use carabiner-type hooks I got from Bosun Supplies.
I spliced them to 3-strand nylon figuring my aged and brittle bones
would be less likely to snap given some "sproing" in the line. I seem
to only turn clockwise and thus keep getting hockles. Once every two
days I merilly spin anti-clockwise until all is well once again.

Many thanks,

Howard

I have used aluminum mountain climbing carbiners on my harness for
many years, one long tether, one short tether.
