Silentia is mostly right; ben always tries to pick Humongosaur or fourarms or rath, anything with big muscles. I think that if he (ult. echo) doesn't appear so much is because of the following reason:

-The omnitrix is plenty of aliens with different powers and, on some sort of way, all of them are powerful or better to fight some especific enemy. If ben picks always the ones he likes the most, we only would get to see Humungosaur, fourarms, rath or diamonhead on screen time. Ult. Echo Echo is pretty damn powerful, but the same way he can nearly kill a great enemy just like ultimate kevin, he can nearly be killed by another minor enemy, like the microchip queen.

Besides, even though he's one of my favourite aliens, would people like him so much if he gets all the screen time?
