Both products will work for you. Both are very different in how they work. Here's a start:
CompanionLink syncs ACT! data to the native fields on your phone. This gives you all the built-in functionality that your phone came with.
Handheld Contact syncs ACT! data to a separate application that runs on your phone. This gives you an ACT-like user interface.
The question you need to ask yourself is which option best suits your needs.
