I have not yet posted anywhere on DIS about Tour Guide Mike, but since I just went, I feel like I can say how it helped.
We lived in S. Florida for one year and went to WDW for three days, never got anywhere but the MK (of course I did not know about DIS or TGM).
So on this trip (we went in June) I bought the UG in January of this year, which led me to mousesavers, which led me to DIS, and then to TGM. At that point I was thinking what is $22 more dollars, plus it has a money back guarantee.
At first I was not sure about TGM, like many on here who have posted. I much preferred the "chatty" part of DIS. However, once I started asking questions on TGM's boards, and really getting into the website, I was amazed.
We stayed at the WL from June 17th-24th of this year (I got my AP discount thanks to everyone here on these boards

). I can seriously say that we never waited more than 10 minutes for any ride, (except when my DS who is 3 wanted to ride the motor cars at MK around 7:00 at night, luckily it had been raining so we only waited around 20 minutes, but it was a free night for us).
There probably is a lot here on DIS that is on TGM, but it might be hard to find, DIS is so large and talks about so much (which I love

), but if you want to get into serious planning, then for me TGM was the way to go.
I know that many DIS veterans have tried TGM and say that there is nothing there that they don't know, and that might be true, but I doubt it since Mike or his guides are in the park daily. But as someone who had only been to WDW once before and was going back during a peak season and adding the 50th year celebration, TGM was worth twice/three/four times what I paid for it. I personally had asked the boards at TGM questions who were answered by Mike, who had just been there the day before, or a couple of days before, in this way I do not feel the UG can compete.
My advice, for what it is worth, is to try Tour Guide Mike, and if you don't like it then get your money back. But I bet that most people who try it will agree that it does work.
Anyway, no matter who you go with, what "plan" you are trying, I hope everyone has a magical trip!
