Yeah that's what I was thinking. I trust Libre Office way more since it's free software and I can actually inspect the source code to see what it's doing. I don't trust web apps like these at all.

Loads faster than libre office for one thing.

It loads faster, but it's not faster to use.

- you have to open a new tab.

- then remember the name of the stuff and type it.

- then make sure you are online (not in a plane).

- then type it without all the LO tools such as good spell check and typography fixes.

- then you wait for the generation, download the file and the go to the download directory, and then copy it where you want.

All in all, I'd say it's the same, except you can change stuff in the LO version, work offline, and refer to the one tool that does all the other stuff as well instead of having to manage 1000 of tools to tools such a simple task.
