I can’t stress how much these two website builders are NOT the easy option for building your website.
Dont just take one or two peoples positive experience as an indication of the suitability of these platforms.
Look at these independent reviews. I have just put links to the reviews so you can decide for yourself.
Also, don’t look at websites like https://www.websitebuilderexpert.com/website-builders/squarespace/squarespace-review/ the review is there purely to make Squarespace look good so you buy rom their affiliate link. There is a disclaimer at the top of the page that they are an affiliate.
