I would agree that there is no better or worse in final product and to each his own, so long as you like it and are happy. But, there are some advantages and disadvantages to each system.

I have never found any slurry based system to be as consistent as a non-slurry based system. The clear advantage is you need less hones.

When I hone a lot of razors, I like to do all the razors on the 1k, then all on the 5k, then all on the 8k, etc. This is as fast as picking one up, honing, drying, and putting it back down. If I were using slurry, I'd have to go through the whole slurry process for each razor. But yes, this requires more hones. However, given what I spend on razors and the amount of space all my gear takes up, having a few more hones makes no difference.

It's all about finding what works for you. A synthetic progression works for what I do and how I do it. For others who do different things and do them differently, a different setup may be better suited to the task. My previous post was simply to point out that "can do it" doesn't mean "best way to do it."
