OBR,
CoS, StD, FS, all can have 3+ saves with re-rolls, and a few 2+ saves.
But Death armies and Daemon ones can get after saves as well, and some healing.
Sylvenath also can have good tough units with 3+/4+ and healing
EDIT:
NH can also always be ignore rend with death saves if you are scared of rend.

Most shields do not simply improve saves. They do things like ignore rend, or give a reroll of 1.
All that said, Bonereapers have a frankly insane allegiance ability if you choose Petrifax Elite which gives universal +1 to all save rolls. The Battline Mortek Guard can very easily reroll their save too, which is 3+ with the ability. That is actually statistically better than a 2+ save, though rend hurts it more. That is probably a contender for the best army wide saves in the game right now.
I really hope it gets nerfed!
Well, you can have a full 2+ save armies i
CoS only for turn 1, then its all 3+.
