The latter is robust to your hard drive failing and downloadable in plaintext, too. And it looks better. And you don't have to learn a billion key shortcuts with silly names like "yank" to use it.
And later on, if you decide to keep using it, you can decide to add more shortcuts to your repertoire on a case-by-case basis.
"Yank" is not specific to org-more, btw, but Emacs lingo which predates, of course, a lot of modern UI conventions. Most other names are quite straight-forward.
Note also, that it's not the keyboard shortcut that is called "yank" - the latter is the name of a functionality which you could, if you wanted so, type out in order to use it. The keyboard short is there so you don't have to, and you don't even have to remember the proper name of the function that the shortcut is for.
Or if you later find some other tool that suits you better it may not be possible to move all your data to the other system, or at least prohibitively hard. With org mode, you can probably whip up an extension that mimics that other tool, or else just port you data.
The attraction of org mode is that it it's probably close to the simplest, most primitive way of solving that problem it solves, while also being one of the most easily extensible and customizable (because, emacs).
I don't want primitive, I want convenient and easy to use. I don't want to have to think about how I'm taking notes or write in lisp or "rice" anything.
Also, Emacs is ugly and doesn't sync with my phone. I'm sure I could fix both of those things with sufficient effort, but again, I want to put forth effort solving actual problems, not remaking my Workflowy setup.
This entire topic is microcosm of goofy command line/unix fetishism.
If you want primitive, get a paper notebook. One page per day. That works well, too (seriously).
I'm not claiming Org is a silver bullet, or even better than WorkFlowly or anything else people might use, but it definitely has it's place.
Workflowy has the opposite problem of orgmode. Workflowy owns your data and unless you frequently sync it with your hard drive then you risk losing all of your notes.
However, the best tool is the one that fits your needs and that you're familiar with. That said, would I encourage you to Wade into the orgmode pool? Most certainly!
It syncs to 3 places, of which 2 are encrypted off-site backups. Since I already do everything in Emacs, org mode extends all the tools I already use (links to emails, specific lines in a source code file, contacts, IRC). I spent one hour learning it about 4 years ago and I use it to manage just about everything I have to do on my computer.
If you are not already sold.on Emacs, however, I understand that it can be a tough thing to swallow.

If you also use org-mode for tasks then you can add todo items to your notes that show up in your general agenda, which you may be using to keep track of meetings or events, as well.
in the last year i know two new developers who have written their own emacs configs.
