It is better in ways important to some, but perhaps not everyone. Also, how much better depends on the quality of the supplied curves, which are generally good but can vary.
Split toning needn't be a tool for an obvious look, but a way to subtly nail any hue. I found myself going around in circles, and never quite happy with the ABW hue control, primarily because it's global, and though perhaps technically hue linear throughout the scale (I never measured) just never very attractive to me. You needn't use the triple sectioned hue control heavy handed, you can for example add a little purple to the shadows of your otherwise neutral or cool prints, etc.
One reason I think it works better is illustrated here-

in the supplied image, notice not only how nice and linear the luminosity scale is in the QTR graph, but how smooth the hue lines are compared to the jumpiness of the RGB or ABW output. That may be part of why ABW output never looks "clean" to me.
I hasten to add before anyone gets mad, many are happy with ABW, land on papers and settings that work well and make dandy prints.
The QTR convention is to always supply one curve that is the black inks only, generally labeled warm, since Epson black and lighter black inks are yellowish due to being carbon. Then you blend in other curves at will to get your hue, and they all use only the color ink necessary, never all the color inks. So from a longevity standpoint, over the life of the print it's likely to maintain it's intended hue longer than a mono print made using all the color inks which fade at various rates. To be fair, the longevity tests at Aardenburg are showing the ABW prints to be doing very well, but color inks do have differential fade, and they are bound to change hue eventually.
This is a huge topic that could require a book, or a month long workshop, but additionally-
the RGB driver and the ABW driver by nature have to use up a cluster of dot positions to make up a tone, and that cluster will contain dots of ink of all the colors, that's how it works. The ABW driver less, but still all the colors.
Therefore dot positions that could have been used to define file detail are instead utilized for hue. Good ink setups for mono chrome usng a RIP, light inks to full advantage, and only the color ink absolutely necessary, can use more dot positions to define file info if it is present, and write more information to paper.

even though this was done with StudioPrint, QTR is capable of the same advantage. All this with OEM ink.
Even though I do not personally use QTR, I think it is the greatest and simplest tool available for B&W artists printing with ink on Epsons. It's for B&W, not for color, and controls the inks in ways appropriate for that specifically, AND gives the kind of control discerning B&W artists would want to personalize their results. Additionally, the next step, monochromatic ink sets, it hands the designer the tools for that as well...
Enough.. too much...
So download it and try it for free, if you like it give Roy his measly $50. OK the docs suck, what do you want for $50????
