To possibly answer your question, think about conveniences that every editor gives you: Editing per (UFT8) character, instead of code points, or bytes or even bits. Would that make you less efficient? I'm sure it would.

Conversely, saying "delete in parens" instead of "move forward 5, delete back 10" is also a real gain.

That being said, use what you have. With editing, and navigating the same file, Vim or it's emulations are almost always better, but most editors offer great cross-file features you should also use, like the "shift shift" in Intellij IDEs, or "ctrl-p" in vscode.
