My recommendation to anyone is to use ask the most then tell it to “implement what we discussed” when it looks good.
Hope that helps
In my experience, next edit is a significant net positive.
It fixes my typos and predicts next things I want to do in other lines of the same file.
For example, if I fix a variable scope from a loop, it automatically scans for similar mistakes nearby and suggests. Editing multiple array values is also intuitive. It will also learn and suggest formatting prefences and other things such as API changes.
Sure, sometimes it suggests things I don't want but on average it is productive to me.
It's also somehow tracking what I look at, because I can look up an API and then return to the original source file and the first autocomplete suggestion is exactly what I was looking up, even though there would be no context to suggest it.
It's really quite magical, and a whole different level from Copilot.
That hasn't been my experience with Copilot next edit feature.
It often understands exactly what I'm doing and I'm able to just tab tab around the file. Like my example about variable loop scope fixing.
My experience is that Copilot does everything you said including considering files I viewed previously to better understand what I'm trying to do.
