The Nitecore P15 looks to be in an entirely different class of lights from all others listed in the original post.

The P15 is an 18650 size utility light. It’s fairly large… too big for EDC, and not the latest model so the price is relatively low. It has a comparatively large reflector and a lot of mass so gives more throw and can probably sustain it longer.

All the other lights are keychain size with sealed internal batteries. It’s not surprising they have less output and less throw. They’re meant for an entirely different purpose… keychain EDC.

It’s not a fair comparison at all. If you’re going to compare lights to see which is the best value, at least compare to lights in the same class (1x18650 with recharging).
