I would agree, while the UI looks nice on first glance I think some UI concepts are way weird and it's over all overloaded.
On Android I quite like SchildiChat, which is a simple-at-first-look client.

Meanwhile, the nice thing about Matrix is you can use whatever app you like - e.g. SchildiChat is a fork of Element Android, FluffyChat's good too, so use whatever floats your boat.
