But it is not the interpretation of others.
Right now, at this moment, I know which one of the helicopters I would rather outfit my military with.
Who knows what that will be in ten years?
In addition, the Apache has indeed been upgraded many times, and continually improved upon. The latest AH-64E shows this.

But now, it will ultimately be replaced by the newer breed of Future Vertical Lift (FVL) machines like some versions of Bell's V-280, Sirkorskys Defiant, and others, which will include attack platforms.
In the mean time, it is one of the, if not the, absolute best attack helicopters available at this time.
