Adidas make great boxing shoes, I far prefer them to any other brand. So they've got a bit of history. Reebok also make some decent bag gloves (the big 16-18oz ones). I think the likes of Reyes, Grant & Everlast will always be fine, because the quality of their product ensures that people who want the best will go to them over the name brands. No one will ever be able to replicate the quality they put out.
