Clearly a lot of people find it so. In most cases I find it easy enough to arrive at a very acceptable print without split-grade. Similarly, I don’t feel a need for f-stop timing.
Ah, but there’s the rub. I may wallow in the sheer beauty of a nice silver gelatine print, but I always wonder whether I could do better. Hence my interest in @Craig’s assertion that a split-grade print is intrinsically better than a single-grade print of the same contrast. Always open to being persuaded if it isn’t just a question of preference.
I was acquaintances with Gene Nocon when I was young. Of course we had a lot of discussions about printing. He wanted to get to the simplest result in the quickest time. He used to say he could have the print in three sheets of paper. He used mostly graded papers too from what I remember. If that is your goal, then it is a perfect way for you to print whether it is on graded or VC papers.
Yes, wondering will get you chasing your tail, but what you learn in the process will make you a better printer. Like I wrote earlier in this thread, I've gone down the rabbit hole more than once with equipment and methods. I learned along the way and I became a better printer I'd like to think.
No, a split grade print isn't intrinsically better. In the example Craig showed it is obvious that the contrast and exposure are different so there is no direct comparison that can be made or any conclusions that can be drawn. The obvious difference is the result of a logical fallacy on his part. Doremus already touched on that.
Split printing is faster overall, usually. If one starts with a grade and it is wrong then one starts chasing one's tail with grades and exposures, especially if the experience level isn't that high. With split printing two test strips is usually all that is needed to get started.
Any way you get to a print that you like is a good way. One can be wrong about facts, but opinions are a different thing altogether. In the end, if one likes one's prints, then that is all that matters.
