You need to look at whether or not you want to say "TO a person" or "for a person" This often has to do with what prcecedes (comes before) it -- sometimes an adjective, sometimes a verb. Try this: Add the "to me" or "for me" to the end of the sentence instead and read it to yourself to see what sounds better. It sounds okay to me. = To me, it sounds okay. GOOD It sounds okay for me --WRONG. (because it's TO MY EARS, it sounds okay) It is good deal for most people = For most people, this is a good deal. it's a good deal to most people. - not incorrect but a little weird. (To most people, this sounds like a good deal, but it's not) So both are correct here. In your example, you could use either one. You could avoid this problem by using "In my opinion" or "I believe" :-)
