For me it's not push per se (Direct or otherwise) that's the issue. Pull email with a reasonably short automatic poll time is ok (many carriers have 'unlimited' data plans anyway now). But for me the BB solution scores because:

- Still class leading battery life. After the battery goes flat, it's "mail when recharged" anyway

- It just works like it's supposed to. Few quirks, problems or dramas. Dependable. I'm not sure if the end-to-end MS solution is as robust yet.
