Not sure if this is the right section to post this, so apologies if not!

"The better performance"

Is this correct English? It's for an advert title.

Thanks.

It's difficult to say. There is probably some implied (at least ) context and it may be acceptable. Besides, in advertisements, many things that would not be acceptable in formal contexts are fine.
