I didn't stop believing in god because I left the JWs. I stopped being a JW when I realized I didn't believe in god. Because I faded so slowly and only left when that happened, it was never a question of hate or disillusionment. I came to an answer, it solved a few issues, and it made my next steps a bit clearer. But I've always been pretty flexible and adaptable.
As for convenience, almost any other Christian denomination would have been a considerable improvement over the JWs. Fewer demands, a more relaxed culture and more freedom to search and learn. I'd have been happier finding a different church, of that I have no doubt. But reality had other plans for me...
