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.
I use Affinity designer for design then atom for coding.
The good thing with text editors is that they're interchangeable. I think it has been a while since I had any website done with only one text editor.
The design part is harder. I suck at designing. I had played with the Stylizer a few years ago which was amazing enough, but that's about it, honestly.
Stylizer is CSS editor though. Not complete web editor.
Designing is an entirely different thing than developing - in my opinion, at least.
Sublime text for quick editing
I'd say Visual Studio code is lot better now than Sublime text.
It is not, especially not for quick editing, because it is too slow and eats too much RAM.
I've always used dreamweaver. Before paying for it, I used a lot of other programs, but dreamweaver was just the most reliable and the constantly updating features have been getting really good in these last few years.
