I like the Sagola, especially how few parts it has and how easy to clean it is. As an inexperienced painter, I'm not sure I have it dialed in optimally, and it doesn't seem like many guys are using it for me to confirm my settings.
In any case the Finishline has a problem that I can't find, and I thought it was prudent to have at least two functioning full size guns on hand. Based on DHutton01, Crashtech and some other guys results with the IWATA, and the consensus of the set up for optimal spraying, it seemed like a good choice.
