As usual with these kind of questions, you should always ask yourself: do I feel like I could use some more dmg or be able to be tankier? I don't know about your specific build, but usually endgame builds reach a point where tankiness > DMG because we're already deleting mostly everything. And +1k life translates into quite a bit more if we take paragon board into account (asuming you're picking up the max life nodes). So I'd say #2 if it were me, but that would depend if your build desperately needs more dmg or not. That +dmg is additive so from 500% to 600% is not that big of a deal, and also you didin't crit your temper on #1 making the increased crit chance maybe even out things so yeah
