I don’t have any experience with the Fenix or Holosun lights but I bet you’re going to be be happier with your choice just looking at the specs.
The Holosun has almost 4x as much candela (42,000) compared to the Fenix’s 11,000. On a pistol, it won’t matter as much but on a rifle light, you’re going to appreciate the extra throw/intensity from the higher candela as it’ll make it easier to identify targets further out.
