Does Armodafinil really last that much longer than Modafinil?

I’m debating between trying Modafinil vs Armodafinil and the consensus seems to be that Armodafinil is probably worse because it lasts longer. Therefore, that means more side effects such as insomnia and affecting sleep.

But from what I’m seeing, the half lives look very similar between the two with Armodafinil barely lasting longer. Besides that, Armodafinil looks superior in every other way. I feel like real people’s experiences can be different though, so I wanted to ask you all.

Is there really that big of difference in how long they last? Or does it not really matter?
