I've done coffee foo and had the lot.
None of it beats fresh beans, ground, and vac pot for me.
It's not even a faff. Although it does need scales and a thermo pen!
Hasbean have an app with brew guides, and fheir vac pot one works!
I have a Hario one, but always use a glass rod not a spring filter... they are not as easy to come by, though.
