I'm playing Anthem to explore a world, experience a story, and be a mecha wizard. For me, the appeal is very different between the two games. But we all only have limited time, so I do understand the concern. I personally just don't view them in the same manner.
Also for me (maybe not true for the general populace), I have no issue with picking up one of the games later. Even if I'm too busy to play one at launch, I wouldn't worry about trying it out later. (I get that for multiplayer-dependent games, being there at launch is a good time to play, so maybe I'm approaching this in the wrong way.)
