What's the difference between DVD and Blu-Ray when it's coming to anime collecting ?

I just found one anime with DVD and Blu-Ray version at the same price. I want to know what's the difference between this two when it's coming to Anime collecting. I know that in general Blu-ray has capacity around 100GB where DVD can have up to 8.6 GB maximum. Does both disc versions has anime in Full HD or maybe perhaps just DVD has standard HD quality (720p) ?
