Depends a lot on what you are using IPC for. It seems to me parallelizing computation for performance, isolation/sandboxing, local usage/testing of netowork-able communication, and desktop/system services signaling are the most frequent use cases. Binder and dbus both target and work well for the desktop/system services part, and badly or not at all for the other 3.
