<p>"It would be better for my brother and me."</p>
<p>or</p>
<p>"It would be better for my brother and I"</p>
<p>Which is grammatically correct?</p>
<p>Right away I can see that the 1st one is right since you forgot the period at the end of your second sentence. Just kidding. </p>
<p>This is the real reason why the 1st is correct:</p>
<p>Remove "my brother and" from both sentences. This is what you get:</p>
<p>Sentence 1:</p>
<p>"It would be better for me."</p>
<p>Sentence 2:</p>
<p>"It would be better for I."</p>
<p>Which one sounds better? I think the 1st one does.</p>
<p>the first one is correct. after a preposition, you always put "me" instead of "I"</p>
<p>For all you grammar nerds out there, here's a more technical explanation: “For” is a preposition, and pronouns that come after prepositions are in the objective case, not the nominative case. Therefore, in this example, you must use the object pronoun (me). The sentence with the subject pronoun (I) is wrong. This is also why “Between you and me” is correct, while “Between you and I” is incorrect.</p>
<p>yep, 1st one is correct, if it was like My brother and __ went there (or something like that, it would be I.</p>
<p>Yep, thought so. Friend of mine argued the other, we agreed to do an "ask the audience" type deal. :P</p>
