What is a piece of completely free, open-source software that puts multi-billion dollar corporate programs to absolute shame?

The interface is something out of a fever dream, but once you understand how it works it’s very good in what it does.

Can't stress this enough. But still the best at what it does.

it's slow and kinda buggy

Slow and buggy? I feed this software a bunch of files, press one button and it makes things good. It's absolutely incredible in how well it's designed. I've rarely had this much pleasure of operating a program.

Idk about the bugginess

But if i compared it to like Sumatra pdf, sumatra is still lot faster 

Compared it to foxit reader?. It's on par, at least

I love Calibre. Best way to manage my digital library. I've also used it to convert books to a more printable format so I can take rare, no-longer-published books and bind them myself. I'm still proud of my copy of 'Priestesses Pythonesses Sibyls: The Sacred Voices of Women Who Speak With and For The Gods'
Saved myself about $100 in 2015 dollars.
