Is there anyway I can get the best MS Outlook syncing and the best scheduling program?

I've been testing KeySuite and DateBk5.4a out on the Treo 650 at the same time and I've been getting some inconsistent results that hotsynching does not always resolve. It's frustrating. I can't survive without all of MS Outlook in my 650, but KeySuite's scheduling components are lacking.

Thoughts?
