Either works great. The only difference is the application. They both do their job.
From what I have seen, water-to-air are usually inblock coolers (Deisel engines) or connected to the block.
Air-to-air aftercoolers are the basic one that you will see everywhere.
There isn't a real difference. It's all application based
