Basic law of optics - all else equal, and we are pretty close on these, is that the larger objective is going to get you more image brightness and also a touch more resolution, although the ED on the 663 will make up for some of that.
For general wildlife viewing, either is an excellent choice, but, keep in mind, that much wildlife observation is early and late in the day. The 771 will do a better job in low light.
For digiscoping, though, that ED is a big plus and the 663 will take better pics than the 771, assuming you have enough light to work with in the first place. Keep in mind, though, that photography with any spotting scope is quite limited in low light. If you are serious about wildlife photography and that will sooner or later mean low light photography, your money is best invested in serious SLR/DSLR camera equipment and big long expensive telephoto lenses.
