To be honest, as good as the animation for the 1st episode was, it was basically a collection of separate parts of The Clone Wars, except not as well done. Them on Camino was basically Domino Squad's training on Camino, but not as good. Omega was kinda like the Twi'lek girl Boil and Waxer met on Ryloth, except Omega is annoying.
The best part of episode 1 is how much they improve Crosshair. In episode one he's actually used as an opponent, and is as the episodes progress, they'll continue to evolve him and build him up as a threat.
After episode 1, I must admit it does get better. Hunter and Omega get better character work, and even Wrecker. However, as far as i've gotten into this show, Tech hasn't really gotten any character work. Echo didn't really need any character work because he was already well built up in the first 3 seasons of the clone wars, and it's really nice to reconnect with Echo without him looking like a cybernetic Holocaust victim, which is basically what he was in Clone Wars Season 7.
So in conclusion, the Bad Batch certainly is better than they are in Season 7, but they certainly aren't better than the Clone Wars itself.
