I use Komodo Edit. Pretty light and easy to use.
Wix and Squarespace own your data though and it's like rented space.
I'm a huge fan of Visual Studio Community or Visual Studio Code depending on your needs. I used to use some software called PhpDesigner which I didn't like much but it got the job done. I then moved onto PHPStorm, and stopped using their software after they changed their licensing model. I tried out VSC and found I really liked it. Stable, doesn't slow down, pretty customizable.
I think Visual Studio is too bloated. So for simple stuff, I think visual studio code is a good option.
