I like attention though hype boy is a flop for me. But what I really noticed is that all of them sound virtually the same, I can't distinguish their vocals from eachother. I'd say only Danielle has a voice and tone that I somewhat recognize, otherwise they sound monotonous.
To add on, their vocals are lacking all around tbh. I know 4th gen doesn't focus much on vocals, but their technique and tone leaves much to be desired.
