You can only choose one series to watch, which one would u choose and why?
I personally would choose ultimate alien easily. For me it was perfect, I loved everything about it, and everything was super intense and ben's character was so mature this series almost as invincible was. The ultimate aggregor and ultimate kevin arc were amazing, the introduction of the ultimatrix and the ultimates and so much more made this my favourite ben 10 show. The thing that sucked a bit was not all classic aliens showed up even though some did, and I didn't like that ben was nerfed sometimes due to plot, like when he could have easily finished aggregor off easily before he became ultimate aggregor with any ultimate alien yet he chose brainstorm and got cooked. Or when psyphon beat him as ultimate spidermonkey which made 0 sense at all, but I still enjoyed the show. No hate to omniverse fans, omniverse just wasn't really the best for me, yea it had some good moments but it ruined ben's character by making him more of a kid than he already was back in OS. I didn't like how most of the time the whole show itself was so goofy and filled with jokes, as if af and uaf never existed. Don't get me started on when they made vilgax a joke in OV after he was a madman and a major threat in UAF, he stole the omnitrix twice, killed ben, was able to take down humongasaur, big chill, jetray and destroyed chromastone with ease, now look at him in OV. I'm not talking about him in general, a lot of villains in OV are goofy and lame compared to what we had before in UAF. What do yall prefer, I would like to know what yall think.
