Truth be told, the fact that this thread is (so far) empty suggests to me that the best thing about Tom is/was his calm in the face of others' ranting.
The last few podcasts I've heard him go off on rants about this or that, but hey, he's a short timer now. But mostly he's been dispassionate in temperament, if not actual opinion (there is a difference).
