Really depends on what you want it for brother.
Fastest
Cheapest
Most accurate
Most durable
Want to use a scope and have backup irons
Low light
Long range
If you want a scope option then the Skinner Dovetail peep with factory front or blade front works very well and with the blade sight is pretty stout. You can slide a Hi-Viz front in there and its awesome and probably betwixed the blade and factory bead in durability.
XS Ghost are great too if you don’t want a scope
Both the XS and Skinner Dovetail rear adjust and install easy and once you set them they are set
Many options
