Like That_Guy said, it depends on what type of shooting you do.

I use mine for pest control and to have fun plinking. I want to get into competitions eventually. That being said, I like to have options for whatever I'm doing that day, or just whatever I feel like using.

My dot and 1-4 are on QD mounts and always return to zero after swapping. The MBUS are always there when I feel like using "irons", or proove someone wrong when they say I must be a bad shot without optics (like my grandfather).
