I don't like Seo singing in live performances....Just in MV's

I don't like either of their voices...

sica <3

Most fans (and myself) think Jessica is a better singer. Sure she is nasally but Seohyun sounds out of breathe most of the time.

The Boys is the best example

hmm Seohyun has a more stable voice

ofc Sica~

No competition

i can't even classify Jessica as a very good vocalist, like most people do. she's not really that stable, her voice is incredibely annoying and i don't know, i just don't think she desserves all the hype she gets

Jessica is good but it doesnt feel like she has the confidence to sing live without the back track whereas Seohyun never sings with back track

Seohyun's voice isn't as distinctive but she's a stronger singer

Jessica is definitely better than Seohyun

Seohyun, She is better than Jessica because their manager oppa said the top 3 singers will do the twinkle! and Seohyun is on the mv twinkle ryt? But Jessica is not! so seohyun!

It's hard I think both are good but I choose Sica <333333

Seohyun has a stronger voice, love her singing but jessica? if u like girls with babysinging voice so there u go :)

Technically, Jessica is notches about Seohyun, Jessica is also more stable in live performances, albeit not as consistent(when she's really tired). Seohyun is also a capable vocalist who can easily pass off as a main/lead vocal in any other girl group but she can be a little unstable in her lives(voice cracks and wavers), her vibrato is also not as controlled and rich as Jessica's. In a nutshell,

Technique: Sica>Seo
Tone: Subjective, but I prefer Sica's voice
Power: Seo>Sica
Control: Sica>Seo
Stability: Sica>Seo
Consistency: Seo>Sica
Vocal devices (melismas, vibrato): Sica>Seo

Overall, Jessica > Seohyun

^you could have added ornaments to that list lol
