wordpress, or squarespace, or?

I'm setting up an online life coaching website, and I'm not sure which platform would be best to use? I want something that looks really professional and I like how squarespace pages look, but I'm wondering if there are SEO advantages to one over the other? I'm not great at working with wordpress, so the ease of use of the other options is also a consideration.

I would stick with WordPress, no matter what you want to do you should be able to find a suitable theme or if you want something unique then pay for a custom theme to be developed.

Squarespace looks OK but I wouldn't touch Wix or Weebly.
