Just to get it straight:
Contains DMT:
Mimosa hostilis
Psychotria viridis
Diplopterys cabrerana
Contains Harmalas (which are needed to orally activate DMT, plus they have some psychoactive effects on their own:
Peganum harmala (Syrian rue)
Banisteriopsis caapi (ayahuasca)
Sometimes ayahuasca is the name of just banisteriopsis caapi, sometimes ayahuasca is the name given for a brew containing banisteriopsis caapi + admixture (usually a dmt-containing admixture such as Psychotria viridis)
If it does not contain caapi, but rather rue, it is NOT ayahuasca, but an ayahuasca analogue.
So, you cannot compare mimosa with caapi, those are completely different. In fact, you coudl have a brew with mimosa AND caapi (though thats not a traditional brew, because they are both from different parts of south america). Maybe you want to compare Caapi vs Rue brews? Or using mimosa vs other dmt-containing admixtures?
In that case, I think you should get a variety of answers. There is this thread which there are some related posts (though the title is more about extracted alkaloids/pharma vs ayahuasca)

While rue and caapi both have harmalas, they each have different ratios of harmalas (rue usually having a lot of harmaline, while caapi usually has very little to no harmaline and mostly harmine), plus they each have different other alkaloids in small amounts. This might somewhat change the effects but its hard to describe, also because there are all sorts of variables that may be important (set and setting, dosage, one's expectations to the plant effects, natural variability even within same batch, etc).
Read the linked thread, and do a search for "rue vs caapi" or similar, to have an idea. Otherwise, I think its best that you try it yourself to see each one, and let us know how it goes
