I went with Lied Jungle because despite some issues in exhibit size, it is by far the most exciting exhibit I have visited from the visitors perspective. The next closest are likely their other two major immersion exhibit complexes. CGF is great as well and better for the animals on average, although much of their indoor section is nothing to write home about. It's not nearly as exciting as Lied though imo and it's not much of an exhibit at all for 4 or so months a year as I just experienced.
