Sorry for the late response; I was taking a nap...

I will add another +1 to what ironraven and Blast said.

ETS and ZS are complementary, in my opinion. ETS focuses more on practical short term stuff where the world is not ending (my boat is sinking, so I am stepping up into my liferaft). ZS does that too, but is more about the long-term, totally messed-up situations (my continent is sinking, so I am stepping up into my boat).

I enjoy both a lot.

Also, I lurve fried pickles. They are my favorite Renaissance Festival breakfast.
