Wix or Square Space

[DolceDolce]

Do you prefer Wix or Square Space?

I had a site in WP, and I switched to Wix and don't see to show up as well as I did in organic search results.  I've had the website address the same for 10 years.  The past few years I have used Wix.  I wonder if I should cut my losses and move to Square?  Or is WP really the best for organic search results and I should go back to WP?  

Any suggestions please let me know.
