I like how the metal one looks more, especially since you can get something kind of like the log bench just by chopping down a tree. Sure, it's just a stump, but it's not that far off.
The metal looked great there...I like to put the log one near like a hot spring if get one and the zen one outside of Brewsters like a hip sit down cafe thing, and yellow bench in a general location with a lot of regular foot traffic. Fairy tale is my favorite though.
That first picture was beautiful I would go with that.
