What are your Favorite Chess GUI's And Why..

[hgm]

WinBoard suits my needs perfectly. I especially like the easy and flexible way the tournament manager handles concurrency in engine tournaments. But I also use it a lot for interactive analysis and book editing.

And the best thing is that in the rare case it doesn't do what I want, I can make it do what I want anyway by adding some code, as it is open source.

I guess the only 2 Winboard users have already posted on the thread

Mostly XBoard. It is stable and doesn't crash. Can't say when the last time it crashed.

Sometimes PyChess as it has other variants. Nice looking GUI too + nice PyChess engine.

My own engines have command line "GUIs". I'm so used to command line stuff

For serious engine testing:
CuteChess, Winboard (and may be Banksia in the future)

For all other things:
Scid vs. PC
