And Taemin doing less means he has the tendency to go wrong on lesser occasions (vocal runs which he only does in a high range with resonance if I remember correctly, usage of other registers), but still with that consistency, production itself and very occasional B4s his high notes are better which is what every idol singer is trying to do save for Chen whose lower notes are just <3. Yonghwa is actually nasal throughout and raises his larynx below mid-4th octave.
Basically what's good is too darn good and what's not is just meh. Very meh. I do think he's placed fine, he is above above average if you don't look at the scale ^_^
