I used the original GM in the past and this one seems to work great. I still prefer my current addon, Gmail Checker, because I can delete, archive, mark as read, my email right from the toolbar instead of having to load the gmail page. It's way more convenient.
But this is still a good extension and I would go back to this if I couldn't use Gmail Checker. The one advantage this has over Gmail Checker is that each account can be configured to check mail at different intervals, where as Gmail Checker only has one setting that applies to every account.
I also prefer Gmail Checker's way of organizing the accounts. Having all accounts and email previews under a single toolbar icon.
If you can add these things to Gmail Manager I would switch over in a heartbeat!
