The problem with basically every medical style diaper brand is they often cheapen their diapers to a point where they don't work as good as they should/used to, so any cloth backing will be thin and the diaper itself isn't gonna have enough fluff/sap to be very absorbent.
Most seem to go for a sort of "medical endorsement" so government benefits will pay for them, so then they dont have to worry about satisfied customers as the customers wont actually be using the diapers, just buying the diapers for hospitals and nursing homes and the like to use.
I tried Seni Quatros around 5 years ago and they were a very good cloth backed diaper, the look wasnt the best (then again the look of most medical style diapers is gonna be lacking, they are SUPPOSED to be made to fit a purpose, but once they get cheapened too much they no longer truly serve the purpose they were made for), but they were pretty thick and had a thick/functional cloth backing and they absorbed a lot.
They were basically what a good cloth backed diaper COULD BE, if done right, but I've seen reports that they were cheapened too between then and now.
