New Yorker vs. Continental Town Car vs. Sedan DeVille

I was looking into buying a large 70's luxury sedan and have narrowed my choices down to a 1978 Chrysler New Yorker Brougham, a 1977 Lincoln Continental Town Car, or a 1976 Cadillac Sedan DeVille. I wanted to see if anyone had some extra insight on these cars, and maybe some pros and cons about each. Any info would be helpful. Thanks.
