Build Assistance - EK Based

I currently have 2 different builds I planned on for an EK user. Both have strong points that I like.

Shadow http://poe.sitedyno.com/skill_tree/compute/51419c4b5df9d04838edc9d8e201d9007c9e1f8f[1]

Marauder http://poe.sitedyno.com/skill_tree/compute/6a766fbf8ebcfd003622d9d3ce09956a361e5a62[2]

Can anyone maybe give me an idea which build may end up better in an end game map farm setting?
My main concern is that the Shadow build will not have the tankiness to take any hits.
