I like Sakura, one of my bias in Izone. During Izone, her hype is huge. If we talk about Izone, two names that people will always mentioned was her and wony. Now, in lsf she kinda feel faded in the background lot of times. She's still the one with most fans in lsf but not the one with most hype anymore. Chaewon, Yunjin and Kazuha are really popular among kpop fans now. In izone, she usually went viral a lot time in Korea but not that much anymore now.
I personally thinking that it's because izone concept fits her better. While Chaewon really suits Lsf concept like a glove, Sakura not really fits it perfectly.
