It depends what you're doing, if you're trying to test long range accuracy quite often you need to hold over your target rather than have your crosshairs directly on them so with a laser this would put the dot over the target rather than on it. A well aligned red dot sight would have the same effect as a laser pointer but is a generally more useful tool.

Coop's content did seem to become a lot more formulaic as time went on (though the content itself was far from bad), I don't even think this for lack of trying but more being controlled by the algorithm essentially Pidgeon holing him into just review content in a predictable style. Along with the other personal issues he's had in recent years while we may not know the true reason(s) based on the reasons we do know it is very understandable him leaving foam content creation. As someone who started watching his content around 10 years ago it is sad to see him go but I wish him all the best on his next projects.
