As someone who is Korean, I don't find it all that more efficient or less efficient than Latin characters. I also speak Mandarin, however, and I do appreciate Hangul's terseness.

I wrote my name in Hangul and it came out to 16 "strokes", in English I approximated about 18 strokes (things like m/n I'm not quite sure how to calculate in strokes, so I counted both as a single stroke).

Meanwhile my Chinese name is a whopping 52 strokes. I hate writing my Chinese name.

Latin alphabet's main problem is that it doesn't have any fricative consonants (sh ch j...) so every language has to roll out their own in incompatible fashion leading to confusion. Languages using alphabets specially tailored for them have much more consistent spelling.

also long and short vowels

Latin actually had them I think, they just got lost because romance languages didn't have much use for them, and english famously went proprietary with its great vowel shift.
