than do something or than to do something

[chance22]

In those comparative structures, should there be a bare infinitive following "than" or should there just be an infinitive? e.g.
It's usually easier to follow rules of social behavior than/than to depend on one's own taste.
I'm inclined to use "than to" with reference to the first half of the sentence, but I was told "to" should be omitted here. I really don't know how to make such a choice. Sometimes it seems "than doing" is also OK.
Looking forward to your help.

Sounds better with the 'to' there though it could be omitted.

Thank you. I still wonder what a native speaker will usually use in this kind of sentencs. Are they both OK or one of them is used more often.As in the ex, it's difficult to make a choice between them.

You can use either. I tend to use the "to".
