I agree about being able to distinguish between Vim modes being easier (I notice when I'm in the wrong mode within one or two keystrokes). The other very important thing is being able to recover from using a wrong mode easily. With Vim, it's often a matter of dropping into Normal mode and pressing "u" once or twice. Recovering from closing a private tab will take a bit longer, but you can still live with it. Sailboat and airplane modes are a different story.
