Before I go and rip out and replace my development workflow, is it notably better than auto complete suggestions from CoC in neovim (with say, rust-analyzer)? I'm generally pretty impressed how quickly it gives me the right function call or whatever, or it's the one of the top few.
It's more than choosing the right function call, it goes further than that. If your code has patterns, it recognises and suggests them.
For instance, one I find very useful is that we have this pattern of checking the result of a function call, logging the error and returning, or whatever. So now, every time you have `result = foo()`, it will auto suggest `if (!result) log_error...` with a generally very good error message.
Very basic, but damn convenient. The more patterns you use, the more helpful it becomes.
