Well, nothing is perfect. 
Mint KDE also does an excellent job being based on Kubuntu and for Maui it was quite a tough ride splitting from Netrunner, switching from Kubuntu to Neon in the process and adjusting the model from 6-month release cycles to LTS, including our own S3 repos to simulate the part-rolling approach of Manjaro.
I think its safe to say after 2 years (summer 2018 with the first LTS cycle run) how successfull Maui really is doing.
