This list also has 41 points left to spend, but I'm not sure what to spend it on.

I'm really torn, I think that the first list may be better, but I'd really like to use my new Spass Marine models. Critique on lists is appreciated as well, thanks.

The second list has a target priority problem. You wan't your opponent to shoot those marines, but the DE fall more easily. And the DE score unlike marines.

So then are you suggesting I take the space marine list as a bullet sponge?

No. To put it other way. Witch would you shoot first? Though nonscoring models or soft scoring ones.

Your opponents target priority becomes too easy.
