WhatsApp has the cross-platform compatibility, but I find it horribly slow and inconsistent compared to BBM. When I send something with WhatsApp, I know it will probably get there, but I'm not sure when, in what order, or at what relative time - and it takes a while to figure that out. When I send something with BBM, I know that it will either get there instantly or not at all, and I know that right away. For me, the latter is better.
