Wordpress vs web builders

I’m so attracted to squat space’s themes and SIMPLICITY of use.

But at the expense of knowing Wordpress is way better for seo, I’m not sure it’s worth going for

Wordpress is sorta complicated IMO. I currently use our website to target key words such as:

Scrap car Junk car Cash for cars Etc

Question: Could using squarespace with seo tools like semrush, ahrefs, and moz, possibly compete against Wordpress?

Bonus question: Ahrefs, vs moz, vs semrush

Which is most accurate?
