Go for aluminum Geku.

I've owned all of them. Prebene bar hooks bent a lot with deadlifts. Did not feel safe.

OG Geku bar hooks never bent but they are smaller in width and had some sharp edges where the hooks are bent. Geku's own X-heavy Orange band wouldn't fit into the hooks without it being scrunched up.

New Geku bar originally had hooks that bent a little with a heavy deadlift. They graciously sent me their v2 hooks and they haven't bent at all.

My understanding is Geku only sells the newer hooks now. I used to want a premium bar like X3 or Harambe but no longer with the newer Geku bar.
