so many developers.

Hello there! I'm aware there has been quite a number of posts regarding self processing recently. However, my question is more specific.

There is an incredible number of developers out there. I understand they each have their own specific perks. I'm curious about the aesthetic result of different developers. Is there noticeable variance between types?

Also, I've been reading about Diafine. It seems like the simple answer to self developing. Though, does it really hold its own for quality?

I'd love to hear what anyone has to say about different developers.
