It's better for them to break up/breaking up

Hello guys, how are you?

Today, I would like to bother you a little bit.
There's a sentence I've been having trouble finishing and I'd appreciate your help (if you want to)

The sentence is: "É melhor que eles terminem"

Which one is the correct form?

"It's better for them to break up" or "it's better for them breaking up"?

Could I use both?

I would love your help

Best wishes!

I'd suggest you this one:

"It's better for them to break up"

Due to the fact I find the second one a bit strange at that case.
