Part of the problem here is that some kind of universal answer is being solicited as if a standardized situation exists. Is split printing "always" better? - Is every negative the same? Is every kind of paper the same? Does everyone seek the same look? Of course not.
Split printing is a valuable tool, but just one tool among many worth having in your kit.
Doremus - I have a considerable number of prints of glistening ice and snow, on both older graded papers and newer VC papers. The biggest improvement to the highlights came with pyro (PMK) development of the negatives themselves. Still, earlier VC paper were quite disappointing in this respect. The best later ones were not. And in either case, supplementary unsharp masking could be employed if necessary to bring a level of tonal control to the full range of values, including highlights and deep tones, superior to conventional techniques, including split printing. But there is no one silver bullet. The point is to adapt your materials and technique to the desired endpoint, not to go "over the top" for sake of technique itself (a common mistake of many adolescent learning curves, so to speak).
Frankly, some of my early negs were overdeveloped, and hell to print per highlights even on great graded papers like Seagull G, Brilliant Bromide, Ilfobrom Galerie, and the brief episode of Kodak Elite. In recent years, I've reprinted some of those same negs much better and with considerable ease using MGWT along with simple split printing tweaks. The only problem is that I now have to accept the warm tone that comes with the territory. MG Cooltone is a nice paper in its own right, but not quite as malleable.
But once I had my negative densities worked out way back when, graded Seagull became my critter of choice for cool tone images until they changed it and made it anemic. My learning curve gained traction in numerous ways, and now I can easily handle high contrast situations much better than in my early years, despite the loss of one great paper after another.
I have never resorted to heavy-handed minus or compensation film dev to try to tame highlights, nor flashing, nor soft print developers - all of which tend to crush the wild sparkle and raw power out of those icy mountains scenes I so prize. I have experimented with those methods. There are better ways to do it in my opinion. But the more tools one has at their disposal to choose from, the better.
One tool which has not been mentioned yet is that, yes, there are times when a top end apo enlarging lens will in fact deliver more highlight microtonality than a garden variety lens. Somebody will probably challenge that; but I can actually see the difference in my own prints, and Bob Carnie would probably back me up, because he uses some of the same lenses for similar reasons.
