Well, depending on what you want from it -- the curses UI and autocomplete implementation are very nice, but ipython has a lot of additional features that bpython isn't interested in implemented. I miss the ??function_name feature in ipython that shows the complete source code for a function or class, since the function header isn't always informative enough; I tend to use ipython's bash emulation pretty frequently too.
