I don't know about snap on's latest update, but as of their last update, my Verdict couldn't touch the IDS on powerstrokes. It can do damn near everything else on every other car out there and is my go to scanner 99.9 percent of the time, but it can't do simple stuff like looking at the IPR and ICP while cranking. And the last time I tried, I couldn't control fuel pressure on a Duramax. I spoke with a snap on engineer a while ago and made them aware, so not sure if anything has changed. For now I just grab my tech 2 or IDS when I'm working on diesels.
And personally, I would skip the Ethos completely and see if you can pick up a used Solus pro for the same price or see if you can get a good deal on a new ultra. I would highly recommend a Verdict or Verus, but for most individuals, the cost is out of the question. Their capabilities are amazing however.
