The difference is Infinity War did it better:

-The Wakandans are way more awesome than the Gungans.
-There's no Jar-Jar Binks.
-The Wakandan's barrier actually stops the enemy from getting in, the only reason they let Thanos' army in was to focus their attention away from Vision.
-There's epic super heroes fighting large six legged alien monsters that can down the Hulkbuster armour in a second and not retarded fish aliens fighting paper mache robots.
-There was a lot more at stake in that fight, they were protecting Vision and the Mind Stone from Thanos' army, while the Gungan battle was only a distraction.
-Though the heroes lost when Thanos came, they were kicking major ass before Thanos showed up, while the Gungans lost pathetically.
-The consequences of the battle were real. Half the universe perished because they lost, while the Gungans got off scot free because the control station was destroyed as they were surrendering.

So it would be like copying someone's crappy, poorly explained homework and handing in your own awesome A+ homework.

Bruce Banner fucking around in the Hulkbuster
