I like Lazarus' approach where it tries its best to provide you intelligent completion but if that fails it also does token/keyword/identifier based completion from what it can find in all open files and remembers from previously open files. And it always, always, ALWAYS puts any word it knows/guesses that starts with the characters i type at the front before making any other suggestion. And all that in interactive practically instant speeds. How the hell Visual Studio takes ages (ie. often several seconds) to complete a word i already typed a few moments ago on a 4.2GHz 7700K machine with 32GB of RAM whereas Lazarus happily completes words even on a puny Raspberry Pi, i don't know. Anyone who writes IDEs should work for at least 6 months with Lazarus to understand how to do things right and if their IDE still provides a worse editing experience (i'm not expecting the entire WYSIWYG GUI and object design as this isn't really something everyone cares about, although it'd be nice) after that then they are doing something very wrong. I have issues with Lazarus with the overall UX being very messy, but the editing experience is the best i've seen.
