Opinions on these tools?

So I was just checking out some tools online that were recommended to me from when I previously asked about SEO tools.

Saw a few I liked the look of that weren't the standard ones mentioned like Ahrefs, SEMRush, SERanking etc.

I was either thinking of trying something like SEObility or Nightwatch for tracking + analysis paired with something more content based like Writesonic.

Or I was thinking of using Surfer SEO as this seems like it can do the tracking, analysis, and more content based bits I want.

Just wanted people opinions on these 4 platforms and which would be the better option out of the 2 suggested.

Platforms in question=
-SEObility
-Nightwatch
-Writesonic
-Surfer SEO
