If you are on the fence it's probably better to save the money.
I got conq. because it was a no-brainer for me. First off, I would have bought $25 dollars in pearls eventually. Maybe right off the bat for more pets. So I look at the conq. pack as only a $25 dollar increase over the explorer's pack.
So all in all, I'd say the conq. is $50(for the explorers content) + $25 pearls + $29~37 equaling $104~112.
That doesn't include the housing decor boxes which I'm not sure their use/potential.
So this post was longer than I thought it would be, but this is why I thought the conquers pack was worth buying. That and I'm hopeful and thinking positive toward Daum.
