No, Camotero, I think you are going to find that those writers are true to their areas of expertise.
They are not going to be partisans of Epicurus against their own specialities and interests.
They are going to provide valuable perspective, but you are going to have to be wary of their predispositions.
There is only one reputable academic writer I know of who is not a Stoic, not a Platonist, not an Aristotelian, and who devoted his career to the study of Epicurus because he was so sympathetic to Epicurus' perspective and his importance to the world.
You probably don't need me to repeat his name but of course I will: Norman DeWitt.
Note: As a possible second example we might want to consider Hugh Munro. In reading Munro's commentaries on Lucretius I have found Munro to be a defender of Epicurus/Lucretius' ethical positions against his detractors. I don't have a good list of cites to give you to that, but if I were looking for someone else who apparently devoted his academic career to Epicurus/Lucretius I think Hugh Munro is a good bet.
