Glitch has experienced animators, TADC looks very good. The thing to keep in mind is that 3D animation has more steps, you have 3D modelling, rigging, posing, lighting. Some of the animators have their own channels so you can see how they have their own specialties. The question is what you get out of this additional effort: For the battlefield, prospit, and derse, you could get a lot out of 3D shots. But 2D also gives a lot of freedom, in 2D you don't have to go through the process of modelling and rigging a new model whenever you want to shift the artstyle, which could become very important if they want to shift into a more "hero mode" style, which I'm guessing will happen more often than the comic. In 3D I doubt they would even think about doing the trick with Dave popping out of the phone.
