My first printer was an Anet A8, which lived in the garage due to the noise. I used Octoprint with a webcam to keep an eye on progress, both to abort bad prints and to know when it was done.

I now have a Prusa Mini, which is quiet and small enough to live in a cupboard in my office. It's far more reliable and the print time estimate is so accurate that I don't need Octoprint any more. It also has a USB port instead of SD card, so walking across my office with a USB stick is a viable alternative to sending jobs directly from my desktop browser.

So I guess it depends on your printer - if it's noisy, large, unreliable or you have lots of them, Octoprint is a godsend.
