It only takes a few seconds to download new email when the app opens.
The only advantage I've found with the gmail app is that it gives you full access to your entire gmail history, so searching six years of email is fast and easy. Whereas the exchange gmail only replicates a set history. One other minor benefit to the gmail app is that it is easier (fewer steps) to delete mail.

Turn off "always on mobile data"
Home > Menu > Settings > Wireless & Networks > Mobile Networks > Always-on mobile data
Also, while you are in that Mobile Networks menu, if you get good sprint signal where you live/work (meaning no roaming), click on Roaming, and select "Sprint Only".
I just reported in a Root + OC Widget - 40+ hrs battery life that I am able to get 32.5 hours of battery life. This is with normal usage.
Turning off mobile data doesn't effect receiving emails through the gmail app, and your battery will last much longer when in standby.
