DBZ Kai is a remake of the original, but remastered and some stuff redrawn. However, they made it shorter too. The first DBZ followed the manga and that's why it's over 200 episodes. Kai has some major arcs cut out so you get a series with 200 + reduced to around 50 episodes. I haven't seen Kai yet, but this what I read. My recommendation watch the original first and then Kai. That way you won't lose miss anything. Hope this helps.
Well, I've never watched the original, but from my understanding, this is massively false. Kai is supposed to be extremely true to the manga. The original anime had tons of filler because a weekly anime covers content 3x as fast as a weekly manga (20pages/weekly chapter and 60pages/weekly episode), so all those story arcs were invented to give Akira Toriyama time to write the real story. It really baffles my why JP animation studios work like this rather than alternating which shows they do.
Second, your ratio is exaggerated to the point of hyperbole. It's much closer to a 1:2 ratio than a 1:4 ratio. (just over 50 kai episodes have covered the equivalent of just over 100 original episodes)
