Question

"It's better to do than doing" or "it's better to do than do"
"It's better to walk than take a bus" or "it's better to walk than taking a bus"
which one is correct?

Answer

If you're making a comparison, you generally want to use the same kind of verb conjugation in both sides of the comparison.  So you could say "It's better to walk than to take a bus," using the infinitive in both parts of the comparison.  Or, you could say "Walking is better than taking a bus," using the gerund form of the verb in both instances.  Hope that makes sense!  Good luck!

Answer

It's better to walk than take a bus"

If you want to use 'taking', then the other verb must agree (it must end in 'ing' also):
"It's better to walking than taking a bus"

This is called 'parallelism' - the different parts of the sentence must agree in their form.
