It'd be nice if you actually gave a reason for your position - a reason why apt is unequivocally better than apt-get.
It's true that they do pretty much the same thing, just using slightly different syntax, but that's not really a reason to prefer one over the other.
That all said, for the most common case, namely, installing a new package, I see just two differences between the two commands ("apt install" vs. "apt-get install"):
1) apt has a pretty, colorful, onscreen display. Note that this might wreak havoc if run non-interactively.
2) apt removes the .deb file after it is done installing. apt-get leaves it behind. Normally, this is a plus for apt, but there have been just enough times when I've wanted to inspect the archive file after the install, that I pretty much avoid using apt.
