Among the advantages of this system is the fact that it keeps the traditional naturals, sharps, flats, double sharps and double flats, and assigns them to values based on 3-limit JI, resulting in this system having some level of familiarity for musicians from a traditional background.  However, the disadvantages of this system are that this system relies on too many glyphs, a number of which need to be deciphered, and furthermore, the arrangement of combined and simple accidentals- as well as arrangement of the quartertone accidentals- is counterintuitive.

In addition, a demisharp is approximately a half-sharp, yet here it is called a quarter-sharp, a break with well-established microtonal convention. Finally, two demisharps do not add up to a sharp as one would expect.

Another system proposed by [[User:TallKite|TallKite]] involves simpler notation, with as few extra accidental pairs as possible.  One could do with only one extra pair, only ups and downs (that is, darts), but one would need at least septuple ups, and in practice octuple or more, rendering such a system impractical. As a result, this system has two extra pairs of accidentals.

According to this system, 159edo would be notated with a combination of ups/downs and lifts/drops. The latter (referred to as "slants" here) are written / and \. The ups and downs are used as in 53edo, so one up is 3 edosteps. One lift is 1 edostep. Double-darts are called dup and dud. Triple-darts are trup and trud. Double-slants are dublift and dubdrop.

Instead of ^^^ one could put an actual numeral 3 right on the score, like ^3. If someone actually used just darts and no slants, they would really need to write ^7 and not ^^^^^^^.

This system uses both darts and slants for larger EDOs only when the EDO is multi-ring- that is, the circle of 5ths doesn't include every note- and each ring requires ups and downs. For example 205edo is 5 rings of 41edo, but 124edo is not 4 rings of 31edo. The lifts and drops label the rings. In 159edo, there's a lift ring, a drop ring, and a plain ring. The lift ring is also a double-drop ring, and the drop ring is also a double-lift ring.

Among the advantages of this system is the fact that it keeps the traditional naturals, sharps, flats, double sharps and double flats, and assigns them to values based on 3-limit JI, resulting in this system having some level of familiarity for musicians from a traditional background, while being simpler and more intuitive than the first system. However, among the disadvantages of this system are the lack of quartertone accidentals, and, the need for a prior understanding [[53edo]], which is often not the most straightforward to begin with in terms of notation, as noted by [https://en.wikipedia.org/wiki/53_equal_temperament#Notation Wikipedia's article on 53edo].  The net effect of these two disadvantages is that this system is likely to be less accessible to many microtonal musicians due to many beginners in particular being more likely to have experience with the more straightforward [[24edo]].
One advantage of this notation is that it keeps the traditional naturals, sharps, flats, double sharps and double flats, and assigns them to values based on 3-limit JI. Thus this notation has some level of familiarity for musicians from a traditional background, while being simpler and more intuitive than the first system. This system avoids half-sharps and half-flats because the sharp and the flat are each 15 edosteps. 15 is an odd number, so there are strictly speaking no half-sharps in 159edo. It assumes a prior understanding of [[53edo]], which could be a disadvantage if one comes to 159edo directly, without first exploring 53.

By striking a good balance between the number of accidentals and their semantic consistency, Syntonic-Rastmic Subchroma notation manages to address the weaknesses of both Ups and Downs notation and Sagittal notation, and, as it's derived from Neutral Circle-of-Fifths notation- the de facto standard foundation for notation in 24edo- it is more easily accessible to microtonal musicians at the beginner level, all while retaining Helmholtz-Ellis notation's advantage of fixing the key notation problems that have plagued 53edo itself by means of accounting for the 2.3.5.11 subgroup in general and the syntonic comma specifically.
