Dating or Cam niche for SEO?

Hello everyone, i had domain on casual dating niche for almost 2 years which expired. I used it for social media traffic and now i see the domain has DA 7 authority without any link building. I am ready to buy it again and use it for SEO this time.

The question is, which specific niche would be the best to rank under DATING or CAM?

I know Dating and Cam niche is competitive, but still there are less competitive keywords.

Or maybe something on porn videos or pictures would be ok?

Thank you!
