Obviously, no cat 4 nights at Marriott anymore, since converting your account to RC rewards makes you ineligible for Marriott promos. So yeah, if you stay less than 30 nights average at Marriott hotels, then Ritz Carlton card might be for you. But most frequent travelers have status on at least one airline, so that airline-credit value is marginal.
If you have the RC card, you do not need to convert your account to RC rewards. They essentially are the same rewards system, so you can retain your MR account but it will be boosted to Gold status with your $10,000 Spend on the RC card -- at leat this was how it was explained to me by MR phone reps.
