Just to present the opposing view, Peter Brandt said the following:
I highly detest and object to price-adjusted futures charts. I have never used them and never will. They are highly deceptive. The attempt to get rid of roll gaps results in charts showing historical prices with no resemblance to historical reality.
Here's a nuanced discussion presenting both sides:

My own conclusion: it makes no difference, but one method is more complicated and introduces human error, and wreaks havoc on your TPOs.
Having said all that, FT71 is a tremendous trader, and many other great traders also back adjust. As with everything in this field, its part science, part voodoo, and there is no one size fits all.
