You don't have to convert all your infoboxes to portable style, but if you do, you can focus on the portable syntax. The main drawback of portable infoboxes is that styling is much more difficult since largely only admins can do it and test it.

Also, if you need help with portable infoboxes, asking at the forums of the Portability wiki might get you better help, since they have more experts there.
