Personally, I prefer Red Velvet. The talent they posses is much bigger than that of twice, in all aspects, vocals, dancing and also teamwork, ability to go through with a variety of concerts and not just the cute ones and also musical variety. Red Velvet songs all have a specific trait which makes it different from other songs, whereas all twice songs sound the same.

Well, actually i think twice is better but of course rv is good too.

RedVelvet 9/10
Twice 8/10

I love them both but Ice cream Cake have been my jam for long so.... RedVelvet

I think that Red Velvet is better. Here are the reasons for me
1- I like their style better. I don't prefer listening to twice's songs. Ofc this is optional.

2- Twice is less talented. I mean red velvet's choreographies are harder and vocals are better in my opinion. Even if twice has more talents jyp and producers doesn't let them to, they have easy- cutie concepts. I am not saying that Momo can't dance or smth im talking in general.

3- Red velvet is getting more popular then before, when they first debuted they weren't that recognized so im happy that they are deserving what they are doing. Twice was always popular (and a bit overrated in my opinion)

But i do know that twice improved a lot, it can be seen from their mr removed vids. No hate pls lol. And 2 groups are soo prettyyy and cute/silly 💕💖✌

There's no point in arguing with your friend, both of them are just fine. They have different styles, you can't compare apples with pears. Both groups are beautiful and talented.
