Stop comparing them, please. It seems nowadays we cannot talk about artists without comparing them to someone else. At first, I thought they were pretty similar, but after a few listenings, I did appreciate different voices and sound. They both make electro pop music and share a similar voice, yes, but they still are pretty different to me.
Vanbot is not better than Robyn. Robyn is fucking better 'coz she's older and got so much experience. Vanbot is just starting, but she is fucking perfect too. The time is not the same. When Robyn started the whole world was not as it's now. I hope one day Vanbot n' Robyn make a song together. They're brilliant, there's no reason to put one against the other! We can love both of them!
