I absolutely love autocomplete in VSCode but hate it in Visual Studio while using the same LLM. The big difference for me is the function AcceptNextWord which Visual Studio doesn't have. A long autocomplete suggestion is rarely completely correct and becomes an annoying distraction but one or several words at the beginning of the suggestion are often correct. So, I usually accept only one or few words in VSCode with a hotkey, then type a bit more, then accept few words more etc. That works great for me. Also, I developed intuition in which pieces of code an LLM suggestion would be most probably useless, so I just ignore any suggestions there to avoid unnecessary distraction.
My guess is that many devs who don't like LLM autocomplete, are just unlucky to use a suboptimal UI. As an example, I personally don't understand how some people could like autocomplete in Visual Studio. As you said, it's just too distracting and irritating.
BTW, I use Codeium, not Copilot. But I guess they should have the same autocomplete UI which depends more on IDE than LLM.
