I ordered one for my LnL. Very nice, but I could not get it lined up at exactly 90°. When seating primers I was always pushing at an angle, which made it harder to seat them. I went back to the regular handle, but the roughness and the seam really worked on my hand. Finally went to this:

I like the large size and it is completely smooth, so no eating on the palm of your hand.
I always liked the wood ball on my LCT. Any rough spots smoothed out quickly and it turns in your palm without irritating it.
Probably mostly and individual thing.
