If Attea wasn't there the Incurseons would've lost in Frog of War Part 1. Attea is powerful and smart, not Incurseons in general.

That's because the Highbreed were being secret and stealthy, while the Incurseons had a fullfront assault. The Highbreed didn't have their whole army, which is why Ben's team can beat one Highbreed at a time. When they sent in the whole army they easily destroyed Galvan (who have superior technology). Keep in mind the Highbreed nearly killed all life in the universe, while the Incurseons were only dealing with one planet. I saw that episode, the Highbreed didn't get beaten by force, Ben negotiated with them to stop attacking. If he didn't use the Omnitrix to change their DNA and Rhiney didn't show up, they were seconds away from destroying all life.

You shouldn't judge two species on a single event. Looking at them as a whole, the Highbreed have achieved so much more and are significantly more dangerous.
