So your argument is "they can make more content (NPCs, story) for Fallout 76" (which is a huge undertaking, btw) but a game that is more fun to play, better looking but has loot and difficulty level issues is harder to fix because of loading screens.
Well, ok, fair enough, if loading screens are more important to you than the fun factor, design and gameplay, yes, Fallout 76 is easier to fix because it doesn't have as much loading screens. It really depends on your criteria. For me, because of how Fallout 76 looks and feels, it is a depressing game that can't be fixed at all. Anthem on the other hand can be fixed in almost every aspect but (most likely) the loading screens, which - while annoying - are not such a big deal to me, if everything else works.
Also, you basically said "Bethesda fans don't care the game looks bad" (and visual design is a very important thing for me, for example) so I can use that logic and say that "Anthem fans don't care that there are that many loading screens".
As for the next gen consoles, it will be at least a year before consumers get a chance to buy them (probably more, and the reason MS is most likely going to show next gen prototypes soon is, IMO, because they lost this generation and they want people to get hyped for the next one ASAP), and Anthem has time to become better. By the time the next gen arrives they will either increase the already nice visuals to a PC level and step into the next gen (like Destiny did, it was a cross-gen title) or use the game as a foundation for Anthem 2. Of course, EA may scrap the project, but unless loading screens are a make or break thing for you, Anthem is very much fixable while Fallout is very much unfixable, which was my point.
Again, if Loading screens are more important than gameplay and visuals to you, then I don't know what to tell you. Sure, your opinion is your own, I strongly disagree.
