If you are purely doing web design work, I could maybe recommend Nova for its nice CSS/HTML tooling, but again you can recreate much of this with VSCode anyway. When you factor in Nova is 99 dollars this conversation becomes a lot more difficult when VSCode is such a strong free competitor.
Nova has been through several iterations/product resets, I owned it back when it was called "Coda" too. VSCode by comparison has been relatively stable and its ecosystem a lot healthier.
I'd actually recommend VSCode + another Panic Software app for remote file access on a Mac: Transmit. Transmit is mac native standalone remote filesystem access tool, its basically the tool they built into Nova as a standalone, and 45 bucks:
VSCode + Transmit is IMO the best in class tools on MacOS for this kind of remote access work, although you can easily substitute Transmit for a free tool like CyberDuck or similar too and keep software cost at zero.
