Comparison with object pronouns

[Emanuelli]

In some books, I've seen examples of comparison like these:

a) He is taller than her. / He is taller than she is.
b) I will have less homework than him. / I will have less homework than he will.
c) Sarah is as talkative as us. / Sarah is as talkative as we are.

Is there any difference between the use of object pronoun and the use of subject + auxiliary in sentences with comparison and superlative?

Thanks.

Thanks.

The difference is between informal and formal usage.

Which one of these is Formal?
Thanks in advance.

The formal usage is with the subject pronoun, Iba:

a) He is taller than she is.
b) I will have less homework than he will.
c) Sarah is as talkative as we are.

Of course, with the verb included in the clause, there is no possibility of using the object pronouns 'her', 'him' or 'us'. Even without the clause structure, the subject pronoun is preferred in careful English:

a) He is taller than she.
b) I will have less homework than he.
c) Sarah is as talkative as we.

Ron is absolutely correct that the objective forms are informal, and are often heard in colloquial speech; for any writing, however, they should still be studiously avoided.

In ordinary speech, sentences using the objective forms seem more natural. Thus, we would say:

a) He is taller than her.
b) I will have less homework than him.
c) Sarah is as talkative as us.
