I find the whole subject interesting. A dotted rhythm sounds quite different from a triplet swing sound. It's not really surprising. In a triplet swing rhythm the long note is twice as long as the short note but in a dotted rhythm the long note is three times the length of a short note.

It's been a while since I used Sibelius but I remember that you had a choice of several settings for swing feel. I think that 100% was full triplet swing and there were several settings for less swing.

I used to have a cassette of a Library of Congress recording of Ukrainian immigrants made in the 1920s. Some of the rhythms on that were most strange to my ears. Sort of swing but not as we know it. I may well still have the cassette but now I have nothing to play it on.
