We looked at both the Enclave and the Acadia before we got our Edge. We like them both, however my wife is 5' and the seats would not raise enough for her to see safely. They are a bigger CUV and the seating for 7/8 is nice if you need it. If the visibility issue was absent we would have gotten one of them. Lucky us we decided that we did not need the seating for 7/8 and looked at the Edge which we got on spot.
Things I liked
Acadia - Heads up display, 7 passenger seating, Back row was comfortable, rear audio controls, back up camera dash style and layout Rear A/C
Enclave - 4 year 50k warranty, coated glass for quietness, back row comfort, plush leather, rear A/C
