Due to how my job is defined, autocompletion (the kind that comes with LSP) is usually not an option at all. In the context of my job, the largest part of my effort goes towards RCA (figuring why something doesn't work) in a system mostly not written or designed by me.

This means, that most of the time I deal with a system after it was deployed, often times in a distributed system with most of it only accessible remotely. So, the aspects of my tools that I value (over autocompletion) are integration with shell / terminal, integration with debuggers / tracers / profilers, ability to quickly search / patch files in any format.

Typically, if you look at my monitor (when I'm actually doing something), you'll see Emacs running ansi-term with tmux that shows a bunch of buffers with shells in VMs in different corners of the world, database interactive clients, interactive debuggers, interactive interpreters, vi with multiple tabs open, multiple journalctl -fu xxx buffers, or perhaps kubectl logs -f xxx buffers etc. and outside of tmux some Org buffers with lists of tasks or text that I use to export to JIRA markdown.

(I think my setup would make for an exciting hacker representation in some sci-fi movie! It's all green letters changing rapidly on black background in many small adjacent boxes)

Even in this context, there's some word completion available (eg. in shell, or in Emacs just trying to complete the word by finding similar words in the same buffer), but usually by the time I actually need to write something new (rather than add breakpoints or investigate in some other way), it's crystal clear what needs to be written, and I don't need to leaf through pages of autocompletion to find the right word.

Now, while most developers don't spend that much time figuring out why their software doesn't work, I still think it's a significant portion of any developer's work, so, simply from the standpoint of how much time you spend in what environment it might make sense to go for a tool that's better at editing text than a tool that has better integration with LSP.
