Passporter is my #1 planning tool for a trip to WDW. I too have the deluxe and like that I can removed any sections I don't need before I take my book on vacation!
I have the Unofficial Guide as well and while it does have a good bit of information, I don't think it is anywhere near as user friendly as the Passporter is and is often not complete w/ their information (I have 2/3 of a page of corrections that I'm pulling together to send to them!). I also find the UG to be very "worst case scenerio" with most things WDW related. Very scary for a WDW veteran never mind a 1st time visitor!
I've never done TGM so I can't comment on that. We always travel during the slower times so I've never felt we needed TGM.
