While some may be critical of mgmueller for his extensive collection, I am all for it, as he gives a very uncommon perspective. I'm glad he has chosen to share all these information as well - to me, his actions are comparable to wealthy benefactors from the past who've released their art collection to the public.
I've composed a "comparison matrix" for Mgmueller the Great's comments so far, to better present all this overwhelming amount of data. This will be updated accordingly.
