All console games should have this choice. Even as a member of the PC Master Race, I sometimes choose higher settings in my games and aim for 30fps. Other times I dial it back to get a smooth 60. Depends on the game. I like to make the choice, not the developer.
Usually, I lower shadows a lot to boost frames. So if I ever get this game, I imagine I'll go 60fps. But maybe not...
Choice is good.
I may be totally off base here, but I would honestly prefer the developer spend time optimizing for one target rather than two.
