corfu integrates better with emacs's built-in mechanism (capf), while company offers their own interface, but corfu relies on child frames so it cannot be used in TUI. > projectile It's great as long as you only use it on local projects. Projectile is super slow on remote projects. I have replaced it with project.el (built-in) + projection (extra stuff) and found projection superior on some features.
