For me I try to watch about 2-4 hours of anime a day and when you watch that sheer volume of a show that quickly what you value about it shifts compared to more reasonable amounts.
So in this context I think I enjoyed ZZ more than Zeta simply because the fights are more varied. With Zeta there was this factor of 'I've been watching mechs dodge and shoot in space for an hour' that was nowhere near as bad in ZZ. That being said I think I'll pick out individual episodes from Zeta to rewatch more.
Even though ZZ is a nearly 40 year old show I don't want to spoil it for you, I will say contrary to some claims (despite some surprising and frankly upsetting deaths) it never becomes as bleak as Zeta and ends on a much more hopeful note.
Bright continues to be my favorite character.
