Pro Can open very large files
Pro Great customer support
The developer is very responsive to bug reports and feature suggestions.
Pro Just about every feature is already built in
No searching for plug-ins that may or may not work.
Pro Built-in FTP/SFTP browser
BBEdit can open files directly from, and save them to, any available FTP server. It can also open and save files directly via SFTP (SSH File Transfer Protocol).
Pro Great JAMStack environment
You can build the static site of your dreams without needing any external assistants. Although it does not process LESS, SASS, or SCSS files, BBEdit's includes are very powerful.
Cons
Con Lack of Lua examples
Although Howl can be extended in both Lua and MoonScript, almost all bundles are written in MoonScript. This means that it is a bit harder to find examples if you'd rather write your bundle in Lua. MoonScript can be compiled to Lua but the code won't be as clean and understandable as if it would've been written in Lua by hand.
Con Expensive
It's US$49.99 a single user license
