tenjou tenge anime was pretty watered down compared to the manga. Although I wouldn't read the English adapted manga by CMX because it's highly edited which is sad. And no, the manga wasn't finished and still not done yet. As for Patlabor, I'm a bigger fan of the TV series and not the OVA. I found the OVA too bland. I think the reason why you like the OVA + Movies 1 & 2 is because all of them were written by Mamoru Oshii. Movies 1+2 were great but they also had their flaws from Oshii's writing style. Movie 3 was away from Oshii's style and a little sidestory away from the Patlabor gang but actually came out better.
