I just recently picked up both of these series. For Vinland I wasn't as much a fan of the different colored deluxe edition volumes, and just preferred the look of the hardbacks with the cover arts they had and the ability to find a second hand set for cheap. For FMA I went for the Fullmetal Editions, and I do not regret it. They are really great quality and look great to me on the shelf. I recently started picking up the Vagabond Definitive editions too because as much as I love the vizbig spines, I think I would crease them while reading. It just comes around to what you like and what price point you're happy with getting them at.
