In this case yes, but I would argue this is because the roll grammar is a relatively simple grammar, you have no nesting of different combinators etc. (I have used it in the README because it is simple to understand).
The winnow code also using seperated_pair to ignore the "d" value, which is also adding some logic to retain only the count and sides result.
These libraries have found ways to replace "unwrapping" code with combinators like separated_by or .ignore_then etc. but this still leaves a lot of code for result handling, in my opinon making the code harder to read and reason about, which is what I attempt to improve.
These are of course very subjective things, so another person might prefer the ways the other libraries do this.
One grammar I have been using to make a comparison is a function signature. I tried comparing with nom and chumsky: https://blog.arnedebo.com/posts/a-grammar-first-approach-to-...
