On my tour in South Africa the 180-600 was fine for the wildlife especially on the special reserve areas where wildlife was often close. The bird life however really was my main focus on this year’s trip, and the 600 length was really invaluable, especially when I could take advantage of the close focusing distance the 180-600 has. I have owned a 70-200 F2.8 and given the weight and limited reach I would not take one for a safari trip. I have not yet bought a Zseries 70-200 but I am thinking about it. For my lens choice on the second camera body on international and local birding trips I prefer a 14-30 F4S. It is the best lens for the weight for those dramatic landscape shots.
Lens choices are about personal preferences after all.
