Firstly, your question implies some sort of recovery steps order, which is a very sensitive topic with regard to what is best given the circumstances. I am referring to the fact that one would attempt to image a drive first and if not successful, then perform cleanroom work/or outsource the case. There are many factors involved in considering what recovery step to take first and one is not always better than the other. It depends.
As I predicted, it is really difficult to answer this question in a meaningful manner that will benefit you. The reason I am saying so is because I am biased in terms of the recovery process approach simply because of the tools and number of tools I have available for a case that involves cleanroom work. So, I will comment in a way that would allow you to draw your own conclusions, though, as
Vulcan mentioned, there are other threads in relation to this topic on this forum from which you can absorb a lot of information.
There are all sort of scenarios where an DR tech has to make a decision about how a cleanroom case will be rcovered based on what resources are available as well as the type of drive, drive damage, time available to recover it, and of course, the most important, experience with how to manage those particular aspects in assessing as best as possible the further failure/damage risk vs. sought recovery outcome, which is a perfect image.
So, I am biased because, for the most part, for drives that need cleanroom work, I do not often use DDI. I prefer another tool. However, for somebody who does not have [or prefer] other tools, DDI, or Atola, or whatever else is out there, could be their "go to" #1.
My opinion is that all top hardware imaging tools, such as PC3K/DE, DDI, and Atola, do what they do well. However, which one does what it does very well, it is a matter of preference and at the end of the day which one or what combination of them is most profitable for your business with at least headache possible. For me, each one has features that I wish could incorporate in another to make a "perfect tool" so to speak. However that is not possible and in a way I feel like I would be asking for too much. With dramatization and without associating any of the imagers with the following brands, it's like saying I want to drive a rolls royce, with the sportiness of bmw, off terrain ability of land rover, reliability of honda, gas mileage of toyota, for the cost of dacia.
I can say with confidence that whatever imager you pick as your first tool, it will be profitable, but do NOT expect it to be a savior for every drive.
