While egregiously priced, E3/E5's value is in its security and related offerings (MDE/Purview).

Most password managers can also store TOTP tokens. A few services support registering redundant Yubikeys. Failing that, they usually give you a recovery code with which you can restore access to an account you're locked out of.

Caffeine and modafinil shouldn’t be compared, as they have vastly different activity, history of use, and understanding of effects.

This is merely an anecdote, but I was prescribed modafinil for narcoleptic symptoms. Compared to traditional psychostimulants, I found it to be ineffective with a more severe side effect profile. Of course, YMMV.
