Mitchell or AllData wiring diagrams?

After viewing a bunch of SD and other repair videos, a recurrent complaint is that the redrawn Mitchell color wiring diagrams don't match the actual component wiring in question. Can I get some feedback from users who have used both? How often do you encounter errors in either brand of diagrams? Do you prefer one over the other?

I have used both. Both have the same re-drawn color diagrams AND OEM diagrams.

MOST of the time the redrawn diagrams are accurate. But, you will run into discrepancies, on occasion. The OEM diagrams will help get past these discrepancies.

I prefer All-Data over Mitchell/Shopkey because All-data, depending on your web browser (I use Firefox), will span ALL pages of the schematics, side-by-side, and allow you to zoom and pan ALL pages, at once. You can, also, zoom in by double left-clicking anywhere on the the schematic, and zoom out by double right-clicking. Mitchell makes you use zoom buttons.


Also, when you click on a circuit to highlight it, All-data will highlight that circuit across ALL pages, simultaneously.


With Mitchell/Shopkey, you can only view ONE page of the schematics, at a time. And when you highlight a circuit on ONE page, it does not highlight that circuit on the other pages.

The one thing I like more about Mitchell/Shopkey is the component location feature. All-data, basically, doesn't have this.

I have learned more by being wrong, than I have by being right. :-)

I also prefer all data to Mitchell. For me the navigation is more intuitive and search results yield relevant information where as Shop Key (Snap Ons branded Mitchell) makes you work harder to pick relevant information out of a search.
Also the diagram lay out of all data is much easier to use as Chad said.

Bosch redraws the wiring diagrams and that is where all the redrawn colored wiring diagrams come from. Alldata also includes OEM diagrams. I don't remember if mitchell does or not. Actually contemplating getting identifix at the moment because I don't really like the flow of alldata but I'm getting used to it.

Mitchell, finding information is better and I always tend to go back to Mitchell when I try to use AllData. You type in the keywords for specs and they show right up in the first window and you have all the options. I type "firing order" in mitchell and it gives me the diagrams with cylinder locations and firing order. AllData was giving me irrelevant information when I type that in the search box. I also noted some specs being too high for torque in alldata.
I would think alldata has more OEM data but it appears that they have rewritten a lot of technical data as well. A lot of the information is a copy and paste from the same source from what I have noticed.
