I went looking online and found two Italian consumer publications from recent years that review panettone. Both came up with the Tre Marie brand as their number one choice.The first source, Altroconsumo, stated in 2010 that only Tre Marie (as an industrial and not artisanal product), measured up to their exacting criteria, all the others failed. In 2009, another publication, Il Salvagente, also gave Tre Marie a number one ranking, but also gave high marks to Motta, the most famous brand.
I can't personally substantiate these results, as I've never had the brand. Actually I prefer pandoro.
