I like the leather ones.
The metal ones tend to stick out away from the guitar and form a lever that works the screw loose over time due to strap motion.
The leather ones screw right down flush with the wood so they tend to stay in better... for me, YMMV.
I've found it's good to tighten them up anytime I'm changing strings or otherwise working on the bass.
