I too doubt there would be much difference in quality, if any. And for the reasons you mentioned, I prefer my regular '86 movie release to the digitally remastered one. This probably stems from my own selfish need for nostalgia, but hey, they're my DVDs lol. However, the storage capacity of Blu-Ray would allow for the titanic season 2 to take up less room on the shelf. I am too lazy to look up how many disks it would take up, but wouldn't it be nice to have a complete collection of episodes in just a few disks? In the end, price would be my deciding factor.
