Which moisture barrier to use for replacement siding

I will be replacing my ABTCO siding on the worst wall of my home soon with Hardi or Nichiha cement board. Both require a moisture barrier and I would like to know which one is best? There are Tyvek and Hardi's products which are nonwovens but there are also cheap woven options that are available as well; which are going to do the best job? Both Tyvek and Hardi's product only have a 10-year warranty but the siding on top of them has a 30-year or lifetime warranty; how will that work if the moisture barrier fails?

Thanks
