Sailingdog is right on the money, take your time and enjoy the process/experience. Get a lesson or two, make a friend with a boat (boat owners love to take others out). Chances are you'll Sail the rest of your life, that is how powerful this sport is IMO and it's all about the journey.
To answer the question: my opinion is that Catalina is a better sailing vessel and has better sailing characteristics. BUT my very good friend (owns a huge Hunter) would disagree so it is a little like Ford and Chevy. Best of Luck. gh
