I used to sharpen freehand, but once I got an Edgepro, there was no looking back. I don't care if it's traditional or not, the results are undeniable. As a side benefit, it has helped my freehand skills, as it is easy to see the results as they are happening. So for me it's about 70% Edgepro, and 30% freehand. I've been sharpening for over 30 years also, not that it matters.
I wish the Edgepro would have been invented 30 years ago, would have saved me a lot of aggravation and trial and error. All I want is a sharp knife, and I don't care how it gets there, as long as too much metal isn't removed.
