I remember playing with Cathedral Strings many years ago - Remember them - and how they broke regularly. I have been using Adama strings since I bought the Ovation in 1983 and despite cries to the contrary have never had any problems. When I bought the Taylor about a year ago it came fitted with Elixirs and I have since tried them on all my guitars with no problems. Its really a matter of personal preference at the end of the day.
PS I havn't broken a string since the Cathedral days and thats over 50 years, but I do change strings regularly
