There isn’t one.

Because none of them have all features.

My favourites however are Fractal for desktop and Fluffychat for mobile because they both allow for multiple accounts in one window/app and they look nice, and Fluffychat has features that make it more customisable.

I used to use cinny, but i use fractal now just because its MUCH faster to launch

Nheko is my favourite client, it uses QT and is written in C++, its lightweight and works well on my machines with low resources, it also respects my system theme

Fluffychat on Android mobile. Feels familiar.
