than I/than me

what is better?
a. Than+personal pronoun in nominative case
b. Than+objective pronoun
i.e. She has more time than we or than us.

The answer is “it depends” If you have a few minutes, this is an interesting article (she uses I or me, but it is the same concept) … an-me.aspx

If you don’t have that much time, here are the key paragraphs:

Ken Wilson sums it up best in The Columbia Guide to Standard American English (3):

Than is both a subordinating conjunction, as in She is wiser than I am, and a preposition, as in She is wiser than me.... Since the following verb am is often dropped or “understood,” we regularly hear than I and than me. Some commentators believe that the conjunction is currently more frequent than the preposition, but both are unquestionably Standard.

So remember, than he and than him are both defensible, but not all grammar mavens feel this way. Therefore, I would avoid the prepositional use in formal settings, such as a research paper or job interview. The usage note in The American Heritage Dictionary (4) agrees: “The writer who risks a sentence like Mary is taller than him in formal writing must be prepared to defend the usage against objections of critics.” Unfortunately, defending your grammar during an interview is not the best way to make a good impression.

The quick and dirty tip to determining which pronoun is appropriate after the conjunction than is to figure out the pronoun’s role in the implied sentence by mentally filling in the missing words. Are you trying to say Aardvark likes Squiggly more than I [like Squiggly] or Aardvark likes Squiggly more than [Aardvark likes] me? Sometimes, even if you use the correct pronoun, you may find sentences like I’m taller than he sound too formal in a casual setting. If so, you can use a verb to complete the implied sentence, saying instead, I’m taller than he is. With a verb present, the choice is obvious: subject pronouns are the only option. After all, both sides of the than he/than him debate agree that No bunny knows Easter better than he does.
