Different systems prioritise different things. Briem looks nice until you see how it looks if you're writing really fast - all those zigs and zags blend in.
I'm not sure optimizing for attractive hand-writing is a good idea.

People teaching hand-writing today concentrate on speed and readability rather than beautiful writing. Some cursive forms are good for speed and readability. Taking notes is still an important skill for students, and computer note taking systems aren't always good enough.
There's not much research, but the little bits that exist suggest that taking notes helps people learn.
Some systems, like Briem, are fast and look neat enough but can end up as hard to read zig-zags. http://briem.net/
